* Don't pass inode to ->d_hash() and ->d_compare()Linus Torvalds2013-06-291-5/+2
| | | | | | | | | | | | Instances either don't look at it at all (the majority of cases) or only want it to find the superblock (which can be had as dentry->d_sb). A few cases that want more are actually safe with dentry->d_inode - the only precaution needed is the check that it hadn't been replaced with NULL by rmdir() or by overwriting rename(), which case should be simply treated as cache miss.

* hfsplus: get rid of write_superArtem Bityutskiy2012-07-221-1/+5
| | | | | | | | | | | | | | | | | | | | This patch makes hfsplus stop using the VFS '->write_super()' method along with the 's_dirt' superblock flag, because they are on their way out. The whole "superblock write-out" VFS infrastructure is served by the 'sync_supers()' kernel thread, which wakes up every 5 (by default) seconds and writes out all dirty superblocks using the '->write_super()' call-back. But the problem with this thread is that it wastes power by waking up the system every 5 seconds, even if there are no diry superblocks, or there are no client file-systems which would need this (e.g., btrfs does not use '->write_super()'). So we want to kill it completely and thus, we need to make file-systems to stop using the '->write_super()' VFS service, and then remove it together with the kernel thread. Tested using fsstress from the LTP project. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* hfsplus: add an ioctl to bless filesMatthew Garrett2012-03-201-0/+5
| | | | | | | | | | | | Making an hfsplus partition bootable requires the ability to "bless" a file by putting its inode number in the volume header. Doing this from userspace on a mounted filesystem is impractical since the kernel will write back the original values on unmount. Add an ioctl to allow userspace to update the volume header information based on the target file.

| * fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik2011-07-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The hfsplus backup volume header is located two blocks from the end of the device. In case of device sizes that are not 4k aligned this means we can't access it using buffer_heads when using the default 4k block size. Switch to using raw bios to read/write all buffer headers. We were not relying on any caching behaviour of the buffer heads anyway. Additionally always read in the backup volume header during mount to verify that we can actually read it.

| * hfsplus: fix option parsing during remountChristoph Hellwig2010-11-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | hfsplus only actually uses the force option during remount, but it uses the full option parser with a fake superblock to do so. This means remount will fail if any nls option is set (which happens frequently with older mount tools), even if it is the same. Fix this by adding a simpler version of the parser that only parses the force option for remount. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

This does put significant restrictions on what may be done from the callback, however there don't seem to have been any problems with in-tree fses. If some strange use case pops up that _really_ cannot cope with the rcu-walk rules, we can just add new rcu-unaware callbacks, which would cause name lookup to drop out of rcu-walk mode.

* hfsplus: create correct initial catalog entries for device filesChristoph Hellwig2010-10-141-0/+1
| | | | | | | | | | | | | | Make sure the initial insertation of the catalog entry already contains the device number by calling init_special_inode early and setting writing out the dev field of the on-disk permission structure. The latter is facilitated by sharing the almost identical hfsplus_set_perms helpers between initial catalog entry creating and ->write_inode. Unless we crashed just after mknod this bug was harmless as the inode is marked dirty at the end of hfsplus_mknod, and hfsplus_write_inode will update the catalog entry to contain the correct value.

* hfsplus: remove superflous rootflags field in hfsplus_inode_infoChristoph Hellwig2010-10-141-1/+1

* hfsplus: fix link corruptionChristoph Hellwig2010-10-141-3/+5
| | | | | | | | | | | | | | | | | | | | HFS implements hardlink by using indirect catalog entries that refer to a hidden directly. The link target is cached in the dev field in the HFS+ specific inode, which is also used for the device number for device files, and inside for passing the nlink value of the indirect node from hfsplus_cat_write_inode to a helper function. Now if we happen to write out the indirect node while hfsplus_link is creating the catalog entry we'll get a link pointing to the linkid of the current nlink value. This can easily be reproduced by a large enough loop of local git-clone operations. Stop abusing the dev field in the HFS+ inode for short term storage by refactoring the way the permission structure in the catalog entry is set up, and rename the dev field to linkid to avoid any confusion. While we're at it also prevent creating hard links to special files, as the HFS+ dev and linkid share the same space in the on-disk structure. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

| | | | | | | | | | | | | Most of the extent handling code already does proper SMP locking, but hfsplus_write_inode was calling into hfsplus_ext_write_extent without taking the extents_lock.
