  gfs2: Fix rounding error in gfs2_iomap_page_prepare

The pos and len arguments to the iomap page_prepare callback are not
block aligned, so we need to take that into account when computing the
number of blocks.

Pull yet more SPDX updates from Greg KH:
 "Another round of SPDX header file fixes for 5.2-rc4

  These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
  added, based on the text in the files. We are slowly chipping away at
  the 700+ different ways people tried to write the license text. All of
  these were reviewed on the spdx mailing list by a number of different
  people.

  We now have over 60% of the kernel files covered with SPDX tags:
	$ ./scripts/spdxcheck.py -v 2>&1 | grep Files
	Files checked:            64533
	Files with SPDX:          40392
	Files with errors:            0

  I think the majority of the "easy" fixups are now done, it's now the
  start of the longer-tail of crazy variants to wade through"

Commit 73118ca8baf7 introduced a glock reference counting bug in
gfs2_trans_remove_revoke.  Given that, replacing gl_revokes with a GLF flag is
no longer useful, so revert that commit.

  gfs2: Fix sign extension bug in gfs2_update_stats

Commit 4d207133e9c3 changed the types of the statistic values in struct
gfs2_lkstats from s64 to u64.  Because of that, what should be a signed
value in gfs2_update_stats turned into an unsigned value.  When shifted
right, we end up with a large positive value instead of a small negative
value, which results in an incorrect variance estimate.

If a call to kobject_init_and_add() fails we must call kobject_put()
otherwise we leak memory.

Function gfs2_sys_fs_add always calls kobject_init_and_add() which
always calls kobject_init().

It is safe to leave object destruction up to the kobject release
function and never free it manually.

Remove call to kfree() and always call kobject_put() in the error path.

Pull GFS2 updates from Andreas Gruenbacher:
 "We've got the following patches ready for this merge window:

   - "gfs2: Fix loop in gfs2_rbm_find (v2)"

      A rework of a fix we ended up reverting in 5.0 because of an
      iozone performance regression.

   - "gfs2: read journal in large chunks"
     "gfs2: fix race between gfs2_freeze_func and unmount"

      An improved version of a commit we also ended up reverting in 5.0
      because of a regression in xfstest generic/311. It turns out that
      the journal changes were mostly innocent and that unfreeze didn't
      wait for the freeze to complete, which caused the filesystem to be
      unmounted before it was actually idle.

   - "gfs2: Fix occasional glock use-after-free"
     "gfs2: Fix iomap write page reclaim deadlock"
     "gfs2: Fix lru_count going negative"

      Fixes for various problems reported and partially fixed by Citrix
      engineers. Thank you very much.
