fs: take the ACL checks to common code

2011-07-25T18:30:23+00:00

Replace the ->check_acl method with a ->get_acl method that simply reads an
ACL from disk after having a cache miss.  This means we can replace the ACL
checking boilerplate code with a single implementation in namei.c.

ext3: Convert ext3 to new truncate calling convention

2011-06-25T15:29:51+00:00

Mostly trivial conversion. We fix a bug that IS_IMMUTABLE and IS_APPEND files
could not be truncated during failed writes as we change the code.  In fact the
test is not needed at all because both IS_IMMUTABLE and IS_APPEND is tested in
upper layers in do_sys_[f]truncate(), may_write(), etc.

dquot: cleanup dquot initialize routine

2010-03-04T23:20:30+00:00

Get rid of the initialize dquot operation - it is now always called from
the filesystem and if a filesystem really needs it's own (which none
currently does) it can just call into it's own routine directly.

Rename the now static low-level dquot_initialize helper to __dquot_initialize
and vfs_dq_init to dquot_initialize to have a consistent namespace.

dquot: move dquot initialization responsibility into the filesystem

2010-03-04T23:20:30+00:00

Currently various places in the VFS call vfs_dq_init directly.  This means
we tie the quota code into the VFS.  Get rid of that and make the
filesystem responsible for the initialization.   For most metadata operations
this is a straight forward move into the methods, but for truncate and
open it's a bit more complicated.

For truncate we currently only call vfs_dq_init for the sys_truncate case
because open already takes care of it for ftruncate and open(O_TRUNC) - the
new code causes an additional vfs_dq_init for those which is harmless.

For open the initialization is moved from do_filp_open into the open method,
which means it happens slightly earlier now, and only for regular files.
The latter is fine because we don't need to initialize it for operations
on special files, and we already do it as part of the namespace operations
for directories.

Add a dquot_file_open helper that filesystems that support generic quotas
can use to fill in ->open.

ext3: Use bitops to read/modify EXT3_I(inode)->i_state

2010-03-04T23:20:20+00:00

At several places we modify EXT3_I(inode)->i_state without holding i_mutex
(ext3_release_file, ext3_bmap, ext3_journalled_writepage, ext3_do_update_inode,
...). These modifications are racy and we can lose updates to i_state. So
convert handling of i_state to use bitops which are atomic.

ext3: Remove syncing logic from ext3_file_write

2009-09-14T15:08:16+00:00

Syncing is now properly done by generic_file_aio_write() so no special logic is
needed in ext3.

ext[234]: move over to 'check_acl' permission model

2009-09-08T18:09:04+00:00

Don't implement per-filesystem 'extX_permission()' functions that have
to be called for every path component operation, and instead just expose
the actual ACL checking so that the VFS layer can now do it for us.
