gfs2: Switch to generic xattr handlers

2016-05-13T02:28:05+00:00

Switch to the generic xattr handlers and take the necessary glocks at
the layer below. The following are the new xattr "entry points"; they
are called with the glock held already in the following cases:

  gfs2_xattr_get: From SELinux, during lookups.
  gfs2_xattr_set: The glock is never held.
  gfs2_get_acl: From gfs2_create_inode -> posix_acl_create and
                gfs2_setattr -> posix_acl_chmod.
  gfs2_set_acl: From gfs2_setattr -> posix_acl_chmod.

GFS2: Increase the max number of ACLs

2014-03-19T15:16:24+00:00

This patch increases the maximum number of ACLs from 25 to 300 for
a 4K block size. The value is adjusted accordingly if the block size
is smaller. Note that this is an arbitrary limit with a performance
tradeoff, and that the physical limit is slightly over 500.

gfs2: use generic posix ACL infrastructure

2014-01-26T04:58:22+00:00

This contains some major refactoring for the create path so that
inodes are created with the right mode to start with instead of
fixing it up later.

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.

GFS2: Clean up ACLs

2009-12-03T11:47:35+00:00

To prepare for support for caching of ACLs, this cleans up the GFS2
ACL support by pushing the xattr code back into xattr.c and changing
the acl_get function into one which only returns ACLs so that we
can drop the caching function into it shortly.

GFS2: Fix up system xattrs

2009-12-03T11:43:05+00:00

This code has been shamelessly stolen from XFS at the suggestion
of Christoph Hellwig. I've not added support for cached ACLs so
far... watch for that in a later patch, although this is designed
in such a way that they should be easy to add.
