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

2011-07-21T00:47:59+00:00

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.
Thanks,

pass writeback_control to ->write_inode

2010-03-05T18:25:52+00:00

This gives the filesystem more information about the writeback that
is happening.  Trond requested this for the NFS unstable write handling,
and other filesystems might benefit from this too by beeing able to
distinguish between the different callers in more detail.

Fix remount races with symlink handling in affs

2010-01-27T03:22:24+00:00

A couple of fields in affs_sb_info is used in follow_link() and
symlink() for handling AFFS "absolute" symlinks.  Need locking
against affs_remount() updates.

sanitize ->fsync() for affs

2009-06-12T01:36:14+00:00

unfortunately, for affs (especially for affs directories) we have
no real way to keep track of metadata ownership.  So we have to
do more or less what file_fsync() does, but we do *not* need to
call write_super() there.

affs: convert s_bmlock into a mutex

2008-07-26T19:00:03+00:00

The semaphore s_bmlock is used as a mutex.  Convert it to the mutex API.

[PATCH] fix reservation discarding in affs

2008-05-06T17:45:33+00:00

- remove affs_put_inode, so preallocations aren't discared unnecessarily
  often.
- remove affs_drop_inode, it's called with a spinlock held, so it can't
  use a mutex.
- make i_opencnt atomic
- avoid direct b_count manipulations
- a few allocation failure fixes, so that these are more gracefully
  handled now.
