GFS2: merge window

Here is a list of patches we've accumulated for GFS2 for the current upstream
merge window. Last window's set was short, but I warned that this one would
be bigger, and so it is. We've got 19 patches:

- A patch from Abhi Das to propagate the GFS2_DIF_SYSTEM bit so that newly
  added journals don't get flagged, deleted, and recreated by fsck.gfs2.
- Two patches from Andreas Gruenbacher to improve GFS2 performance where
  extended attributes are involved.
- A patch from Andy Price to fix a suspicious rcu dereference error.
- Two patches from Ben Marzinski that rework how GFS2's NFS cookies are
  managed. This fixes readdir problems with nfs-over-gfs2.
- A patch from Ben Marzinski that fixes a race in unmounting GFS2.
- A set of four patches from me to move the resource group reservations
  inside the gfs2 inode to improve performance and fix a bug whereby
  get_write_access improperly prevented some operations like chown.
- A patch from me to spinlock-protect the setting of system statfs file data.
  This was causing small discrepancies between df and du.
- A patch from me to reintroduce a timeout while clearing glocks which was
  accidentally dropped some time ago.
- A patch from me to wait for iopen glock dequeues in order to improve
  deleting of files that were unlinked from a different cluster node.
- A patch from me to ensure metadata address spaces get truncated when an
  inode is evicted.
- A patch from me to fix a bug in which a memory leak could occur in some
  error cases when inodes were trying to be created.
- A patch to consistently use iopen glocks to transition from the unlinked
  state to the deleted state.
- A patch to fix a glock reference count error when inode creation fails.
- A patch from Junxiao Bi to fix an flock panic.
- A patch from Markus Elfring that removes an unnecessary if.
