fat: restructure export_operations

2013-04-30T01:28:40Z

Define two nfs export_operation structures,one for 'stale_rw' mounts and the other for 'nostale_ro'. The latter uses i_pos as a basis for encoding and decoding file handles. Also, assign i_pos to kstat->ino. The logic for rebuilding the inode is added in the subsequent patches.

fat: Push mnt_want_write() outside of i_mutex

2012-07-30T21:02:50Z

When mnt_want_write() starts to handle freezing it will get a full lock semantics requiring proper lock ordering. So push mnt_want_write() call outside of i_mutex as in other places. CC: OGAWA Hirofumi Signed-off-by: Jan Kara Signed-off-by: Al Viro

vfs: mnt_drop_write_file()

2012-01-04T03:52:40Z

new helper (wrapper around mnt_drop_write()) to be used in pair with mnt_want_write_file(). Signed-off-by: Al Viro

switch a bunch of places to mnt_want_write_file()

2012-01-04T03:52:35Z

it's both faster (in case when file has been opened for write) and cleaner. Signed-off-by: Al Viro

fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers

2011-07-21T00:47:59Z

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.

fs: move inode_dio_wait calls into ->setattr

2011-07-21T00:47:47Z

Let filesystems handle waiting for direct I/O requests themselves instead of doing it beforehand. This means filesystem-specific locks to prevent new dio referenes from appearing can be held. This is important to allow generalizing i_dio_count to non-DIO_LOCKING filesystems. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

fat: remove i_alloc_sem abuse

2011-07-21T00:47:44Z

Add a new rw_semaphore to protect bmap against truncate. Previous i_alloc_sem was abused for this, but it's going away in this series. Note that we can't simply use i_mutex, given that the swapon code calls ->bmap under it. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro
