* [PATCH] mark struct inode_operations const 3Arjan van de Ven2007-02-122-6/+6
| | | | | | | | | | | Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

* [PATCH] Make BH_Unwritten a first class bufferhead flag V2David Chinner2007-02-121-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, XFS uses BH_PrivateStart for flagging unwritten extent state in a bufferhead. Recently, I found the long standing mmap/unwritten extent conversion bug, and it was to do with partial page invalidation not clearing the unwritten flag from bufferheads attached to the page but beyond EOF. See here for a full explaination: http://oss.sgi.com/archives/xfs/2006-12/msg00196.html The solution I have checked into the XFS dev tree involves duplicating code from block_invalidatepage to clear the unwritten flag from the bufferhead(s), and then calling block_invalidatepage() to do the rest. Christoph suggested that this would be better solved by pushing the unwritten flag into the common buffer head flags and just adding the call to discard_buffer(): http://oss.sgi.com/archives/xfs/2006-12/msg00239.html The following patch makes BH_Unwritten a first class citizen.

* [XFS] Remove unused header files for MAC and CAP checking functionality.Eric Sandeen2007-02-104-8/+0
| | | | | | | | | | | | | | | | | | xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.

* [XFS] Fix callers of xfs_iozero() to zero the correct range.Lachlan McIlroy2007-02-102-19/+19
| | | | | | | | | | | | | | The problem is the two callers of xfs_iozero() are rounding out the range to be zeroed to the end of a fsb and in some cases this extends past the new eof. The call to commit_write() in xfs_iozero() will cause the Linux inode's file size to be set too high.

* [XFS] Ensure a frozen filesystem has a clean log before writing the dummyDavid Chinner2007-02-102-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | record. The current Linux XFS freeze code is a mess. We flush the metadata buffers out while we are still allowing new transactions to start and then fail to flush the dirty buffers back out before writing the unmount and dummy records to the log. This leads to problems when the frozen filesystem is used for snapshots - we do log recovery on a readonly image and often it appears that the log image in the snapshot is not correct. Hence we end up with hangs, oops and mount failures when trying to mount a snapshot image that has been created when the filesystem has not been correctly frozen. To fix this, we need to move th metadata flush to after we wait for all current transactions to complete in teh second stage of the freeze. This means that when we write the final log records, the log should be clean and recovery should never occur on a snapshot image created from a frozen filesystem.

* [XFS] Fix sub-block zeroing for buffered writes into unwritten extents.David Chinner2007-02-101-4/+9
| | | | | | | | | | | | | | | | When writing less than a filesystem block of data into an unwritten extent via buffered I/O, __xfs_get_blocks fails to set the buffer new flag. As a result, the generic code will not zero either edge of the block resulting in garbage being written to disk either side of the real data. Set the buffer new state on bufferd writes to unwritten extents to ensure that zeroing occurs.

Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.

* [XFS] Fix a synchronous buftarg flush deadlock when freezing.David Chinner2007-02-101-57/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | At the last stage of a freeze, we flush the buftarg synchronously over and over again until it succeeds twice without skipping any buffers. The delwri list flush skips pinned buffers, but tries to flush all others. It removes the buffers from the delwri list, then tries to lock them one at a time as it traverses the list to issue the I/O. It holds them locked until we issue all of the I/O and then unlocks them once we've waited for it to complete. The problem is that during a freeze, the filesystem may still be doing stuff - like flushing delalloc data buffers - in the background and hence we can be trying to lock buffers that were on the delwri list at the same time. Hence we can get ABBA deadlocks between threads doing allocation and the buftarg flush (freeze) thread. Fix it by skipping locked (and pinned) buffers as we traverse the delwri buffer list.

* [PATCH] Fix XFS after clear_page_dirty() removalDavid Chinner2006-12-211-2/+2
| | | | | | | | | | | | | | XFS appears to call clear_page_dirty to get the mapping tree dirty tag set correctly at the same time the page dirty flag is cleared. I note that this can be done by set_page_writeback() if we clear the dirty flag on the page first when we are writing back the entire page. Hence it seems to me that the XFS call to clear_page_dirty() could easily be substituted by clear_page_dirty_for_io() followed by a call to set_page_writeback() to get the mapping tree tags set correctly after the page has been marked clean.

* [PATCH] dio: only call aio_complete() after returning -EIOCBQUEUEDZach Brown2006-12-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only time it is safe to call aio_complete() is when the ->ki_retry function returns -EIOCBQUEUED to the AIO core. direct_io_worker() has historically done this by relying on its caller to translate positive return codes into -EIOCBQUEUED for the aio case. It did this by trying to keep conditionals in sync. direct_io_worker() knew when finished_one_bio() was going to call aio_complete(). It would reverse the test and wait and free the dio in the cases it thought that finished_one_bio() wasn't going to. Not surprisingly, it ended up getting it wrong. 'ret' could be a negative errno from the submission path but it failed to communicate this to finished_one_bio(). direct_io_worker() would return < 0, it's callers wouldn't raise -EIOCBQUEUED, and aio_complete() would be called. In the future finished_one_bio()'s tests wouldn't reflect this and aio_complete() would be called for a second time which can manifest as an oops. The previous cleanups have whittled the sync and async completion paths down to the point where we can collapse them and clearly reassert the invariant that we must only call aio_complete() after returning -EIOCBQUEUED. direct_io_worker() will only return -EIOCBQUEUED when it is not the last to drop the dio refcount and the aio bio completion path will only call aio_complete() when it is the last to drop the dio refcount. direct_io_worker() can ensure that it is the last to drop the reference count by waiting for bios to drain. It does this for sync ops, of course, and for partial dio writes that must fall back to buffered and for aio ops that saw errors during submission. This means that operations that end up waiting, even if they were issued as aio ops, will not call aio_complete() from dio. Instead we return the return code of the operation and let the aio core call aio_complete(). This is purposely done to fix a bug where AIO DIO file extensions would call aio_complete() before their callers have a chance to update i_size. Now that direct_io_worker() is explicitly returning -EIOCBQUEUED its callers no longer have to translate for it. XFS needs to be careful not to free resources that will be used during AIO completion if -EIOCBQUEUED is returned. We maintain the previous behaviour of trying to write fs metadata for O_SYNC aio+dio writes.
