| * quota: move code from sync_quota_sb into vfs_quota_syncChristoph Hellwig2010-03-054-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Currenly sync_quota_sb does a lot of sync and truncate action that only applies to "VFS" style quotas and is actively harmful for the sync performance in XFS. Move it into vfs_quota_sync and add a wait parameter to ->quota_sync to tell if we need it or not. My audit of the GFS2 code says it's also not needed given the way GFS2 implements quotas, but I'd be happy if this can get a detailed review.

* | GFS2: ordered writes are backwardsDave Chinner2010-03-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we queue data buffers for ordered write, the buffers are added to the head of the ordered write list. When the log needs to push these buffers to disk, it also walks the list from the head. The result is that the the ordered buffers are submitted to disk in reverse order. For large writes, this means that whenever the log flushes large streams of reverse sequential order buffers are pushed down into the block layers. The elevators don't handle this particularly well, so IO rates tend to be significantly lower than if the IO was issued in ascending block order. Queue new ordered buffers to the tail of the ordered buffer list to ensure that IO is dispatched in the order it was submitted. This should significantly improve large sequential write speeds. On a disk capable of 85MB/s, speeds increase from 50MB/s to 65MB/s for noop and from 38MB/s to 50MB/s for cfq.

* | GFS2: Remove loopy umount codeSteven Whitehouse2010-03-015-37/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | As a consequence of the previous patch, we can now remove the loop which used to be required due to the circular dependency between the inodes and glocks. Instead we can just invalidate the inodes, and then clear up any glocks which are left. Also we no longer need the rwsem since there is no longer any danger of the inode invalidation calling back into the glock code (and from there back into the inode code).

* | GFS2: Metadata address space clean upSteven Whitehouse2010-03-0113-95/+101
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the start of GFS2, an "extra" inode has been used to store the metadata belonging to each inode. The only reason for using this inode was to have an extra address space, the other fields were unused. This means that the memory usage was rather inefficient. The reason for keeping each inode's metadata in a separate address space is that when glocks are requested on remote nodes, we need to be able to efficiently locate the data and metadata which relating to that glock (inode) in order to sync or sync and invalidate it (depending on the remotely requested lock mode). This patch adds a new type of glock, which has in addition to its normal fields, has an address space. This applies to all inode and rgrp glocks (but to no other glock types which remain as before). As a result, we no longer need to have the second inode. This results in three major improvements: 1. A saving of approx 25% of memory used in caching inodes 2. A removal of the circular dependency between inodes and glocks 3. No confusion between "normal" and "metadata" inodes in super.c Although the first of these is the more immediately apparent, the second is just as important as it now enables a number of clean ups at umount time. Those will be the subject of future patches. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* GFS2: Fix bmap allocation corner-case bugSteven Whitehouse2010-02-121-1/+1
| | | | | | | | | | | | | This patch solves a corner case during allocation which occurs if both metadata (indirect) and data blocks are required but there is an obstacle in the filesystem (e.g. a resource group header or another allocated block) such that when the allocation is requested only enough blocks for the metadata are returned. By changing the exit condition of this loop, we ensure that a minimum of one data block will always be returned. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* GFS2: Extend umount wait coverage to full glock lifetimeSteven Whitehouse2010-02-035-7/+17
| | | | | | | | | | | | | | Although all glocks are, by the time of the umount glock wait, scheduled for demotion, some of them haven't made it far enough through the process for the original set of waiting code to wait for them. This extends the ref count to the whole glock lifetime in order to ensure that the waiting does catch all glocks. It does make it a bit more invasive, but it seems the only sensible solution at the moment. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* GFS2: Wait for unlock completion on umountSteven Whitehouse2010-02-034-1/+13
| | | | | | | | | | This patch adds a wait on umount between the point at which we dispose of all glocks and the point at which we unmount the lock protocol.

* GFS2: Don't withdraw on partial rindex entriesBenjamin Marzinski2010-02-011-5/+0
| | | | | | | | | | | | | ince gfs2 writes the rindex file a block at a time, and releases the exclusive lock after each block, it is possible that another process will grab the lock in the middle of the write. Since rindex entries are not an even divisor of blocks, that other process may see partial entries. On grows, this is fine. The process can simply ignore the the partial entires. Previously, the code withdrew when it saw partial entries. Now it simply ignores them. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* GFS2: Fix locking bug in renameSteven Whitehouse2010-01-081-2/+4
| | | | | | | | | The rename code was taking a resource group lock in cases where it wasn't actually needed, this caused problems if the rename was resulting in an inode being unlinked.

* GFS2: Ensure uptodate inode size when using O_APPENDSteven Whitehouse2010-01-081-2/+36
| | | | | | | | | | | | | | The VFS reads the inode size during generic_file_aio_write() but with no locking around it. In order to get the expected result from O_APPEND opens, this patch updated the inode size before calling generic_file_aio_write() There is of course still a race here, in that there is nothing to prevent another node coming in and extending the file in the mean time. On the other hand, when used with file locking this will ensure that the expected results are obtained. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* sanitize xattr handler prototypesChristoph Hellwig2009-12-164-54/+41
| | | | | | | | | | | | | | | | | | | | | Add a flags argument to struct xattr_handler and pass it to all xattr handler methods. This allows using the same methods for multiple handlers, e.g. for the ACL methods which perform exactly the same action for the access and default ACLs, just using a different underlying attribute. With a little more groundwork it'll also allow sharing the methods for the regular user/trusted/secure handlers in extN, ocfs2 and jffs2 like it's already done for xfs in this patch. Also change the inode argument to the handlers to a dentry to allow using the handlers mechnism for filesystems that require it later, e.g. cifs.

* GFS2: Fix glock refcount issuesSteven Whitehouse2009-12-031-13/+8
| | | | | | | | | | | | | | This patch fixes some ref counting issues. Firstly by moving the point at which we drop the ref count after a dlm lock operation has completed we ensure that we never call gfs2_glock_hold() on a lock with a zero ref count. Secondly, by using atomic_dec_and_lock() in gfs2_glock_put() we ensure that at no time will a glock with zero ref count appear on the lru_list. That means that we can remove the check for this in our shrinker (which was racy). Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* GFS2: drop rindex glock to refresh rindex listBenjamin Marzinski2009-12-031-2/+6
| | | | | | | | | | | | When a gfs2 filesystem is grown, it needs to rebuild the rindex list to be able to use the new space. gfs2 does this when the rindex is marked not uptodate, which happens when the rindex glock is dropped. However, on a single node setup, there is never any reason to drop the rindex glock, so gfs2 never invalidates the the rindex. This patch makes gfs2 automatically drop the rindex glock after filesystem grows, so it can refresh the rindex list.

* GFS2: Tag all metadata with jidSteven Whitehouse2009-12-034-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two spare field in the header common to all GFS2 metadata. One is just the right size to fit a journal id in it, and this patch updates the journal code so that each time a metadata block is modified, we tag it with the journal id of the node which is performing the modification. The reason for this is that it should make it much easier to debug issues which arise if we can tell which node was the last to modify a particular metadata block. Since the field is updated before the block is written into the journal, each journal should only contain metadata which is tagged with its own journal id. The one exception to this is the journal header block, which might have a different node's id in it, if that journal was recovered by another node in the cluster. Thus each journal will contain a record of which nodes recovered it, via the journal header. The other field in the metadata header could potentially be used to hold information about what kind of operation was performed, but for the time being we just zero it on each transaction so that if we use it for that in future, we'll know that the information (where it exists) is reliable. I did consider using the other field to hold the journal sequence number, however since in GFS2's journaling we write the modified data into the journal and not the original data, this gives no information as to what action caused the modification, so I think we can probably come up with a better use for those 64 bits in the future.

Setting setting statfs_quantum to 0 will also turn on the statfs_slow tunable. statfs_percent accepts an integer between 0 and 100. Numbers between 1 and 100 will cause GFS2 to do any early sync when the local number of blocks free changes by at least statfs_percent from the totoal number of blocks free.
