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,

bad_inode_permission() is safe from RCU mode

return -EIO; is *not* a blocking operation, thank you very much.
Nick, what the hell have you been smoking?

kill ->dir_notify()

2008-12-31T23:07:43+00:00

Remove the hopelessly misguided ->dir_notify().  The only instance (cifs)
has been broken by design from the very beginning; the objects it creates
are never destroyed, keep references to struct file they can outlive, nothing
that could possibly evict them exists on close(2) path *and* no locking
whatsoever is done to prevent races with close(), should the previous, er,
deficiencies someday be dealt with.

[PATCH] sanitize ->permission() prototype

2008-07-27T00:53:14+00:00

* kill nameidata * argument; map the 3 bits in ->flags anybody cares
  about to new MAY_... ones and pass with the mask.
* kill redundant gfs2_iop_permission()
* sanitize ecryptfs_permission()
* fix remaining places where ->permission() instances might barf on new
  MAY_... found in mask.

The obvious next target in that direction is permission(9)

iget: introduce a function to register iget failure

Introduce a function to register failure in an inode construction path.  This
includes marking the inode under construction as bad, unlocking it and
releasing it.

sendfile: remove bad_sendfile() from bad_file_ops

2007-07-10T06:04:15+00:00

do_sendfile() prefers splice over sendfile, so it should not trigger
(directly, at least).
