GFS2: Pull request (merge window) (redo)

[Bob Peterson]

Hi Linus,

I've adjusted this pull request to have a proper diffstat generated by
git merge to a temporary branch, as I did the last time this happened.

So you can pull this one, but probably after Ted's merge request:
https://lkml.org/lkml/2017/11/12/256

Please consider pulling the following changes for the GFS2 file system.

Regards,

Bob Peterson

  gfs2: Allow gfs2_xattr_set to be called with the glock held (2017-10-31 14:26:59 +0100)

----------------------------------------------------------------
We've got a total of 17 GFS2 patches for this merge window. The
patches are basically in three categories: (1) patches related to
broken xfstest cases, (2) patches related to improving iomap and
start using it in GFS2, and (3) general typos and clarifications.

Please note that one of the iomap patches extends beyond GFS2 and
affects other file systems, but it was publically reviewed by a
variety of file system people in the community.

1. Andreas has a patch that simply renames variable 'bsize' to 'factor'
   to clarify the logic related to gfs2_block_map.
2. He also has a patch to correctly set ctime in the setflags ioctl,
   which fixes broken xfstests test 277.
3. He also fixed broken xfstest 258, due to an atime initialization
   problem.
4. He also fixed broken xfstest 307, in which GFS2 was not setting
   ctime when setting acls.
5. He has a patch to switch general iomap code from blkno to disk
   offset for a variety of file systems.
6. He has a patch to add a new IOMAP_F_DATA_INLINE flag for iomap
   to indicate blocks that have data mixed with metadata.
7. I contributed a patch to make inode height info part of the
   'metapath' data structure to facilitate using iomap in GFS2.
8. I have a patch to start using iomap inside GFS2 and switch GFS2's
   block_map functions to use iomap under the covers.
9. I have a patch to switch GFS2's fiemap implementation from using
   block_map to using iomap under the covers.
10. Andreas has a patch to implement SEEK_HOLE and SEEK_DATA via
    iomap in GFS2.
11. I have a patch related to journaled data pages not being properly
    synced to media when writing inodes. This was caught with xfstests.
12. I have a patch to fix another failing xfstest case in which
    switching a file from ordered_write to journaled data via set_flags
    caused a deadlock.
13. Andreas has a patch to fix failing xfstest case 066, which was
    due to not properly syncing dirty inodes when changing extended
    attributes.
14. Andreas fixed a minor typo in a comment.
15. Andreas contributed a patch to partially fix xfstest 424, which
    involved GET_FLAGS and SET_FLAGS ioctl. This is also a cleanup
    and simplification of the translation of flags from fs flags to
    gfs2 flags.
16. He also added support for STATX_ATTR_ in statx, which fixed broken
    xfstest 424.
17. He also contributed a fix for failing xfstest 093 which fixes a
    recursive glock problem with gfs2_xattr_get and _set.
