    [PATCH] generic acl support for ->permission · 42017c2e
    Christoph Hellwig authored
    Currently we every filesystem with Posix ACLs has it's own reimplemtation
    of the generic permission checking code with additonal ACL support.  This
    patch
    
    - adds an optional callback to vfs_permission that filesystems can use
      for ACL support (and renames it to generic_permission because the old
      name was wrong - it wasn't like the other vfs_* functions at all)
    
    - uses it in ext2, ext3 and jfs.  XFS will follow a little later as it's
      permission checking is burried under several layers of abstraction.
    
    From: Dave Kleikamp <shaggy@austin.ibm.com>
    
      jfs doesn't currently set MS_POSIXACL (it doesn't require the acl mount
      option), so this test would fail here.  The patch below will set it.
