  gfs2: Add a few missing newlines in messages (2018-01-30 10:32:30 -0700)

----------------------------------------------------------------
We've got 30 patches for this merge window. These generally fall into
five categories: (1) code cleanups, (2) patches related to adding
PUNCH_HOLE support to GFS2, (3) support for new fields in resource group
headers, (4) a few bug fixes, and (5) support for new fields in journal
log headers. These new fields, which were previously unused, are designed
to make it easier to track down file system corruption, and allow fsck.gfs2
to make more intelligent decisions when finding and fixing file system
corruption.

1. Abhi Das contributed a patch to trim the ordered writes list, which
   used to grow uncontrollably until unmount.
2. Abhi also added a second patch to trim the ordered writes list.
3. Andreas Gruenbacher removed an unused parameter from function
   gfs2_write_jdata_pagevec.
4. Andreas also removed a pointless BUG_ON.
5. Andreas cleaned up an error patch in trunc_start.
6. Andreas removed some unused parameters from truncate.
7. Andreas made gfs2_journaled_truncate more efficient.
8. Andreas cleaned up the support functions for truncate.
9. Andreas fixed metadata read-ahead for truncate to make it faster.
10. Andreas fixed up the non-recursive truncate code.
11. Andreas reworked and renamed function gfs2_block_truncate_page.
12. Andreas generalized the non-recursive truncate code so it can
    take a range of values for punch_hole support.
13. Andreas introduced new PUNCH_HOLE support that take advantage
    of the previous patches.
14. Andreas contributed a patch to add fallocate with PUNCH_HOLE.
15. Andreas fixed some typos in the comments.
16. Andreas added function gfs2_max_stuffed_size to replace a piece
    of code that was needlessly repeated throughout GFS2.
17. Andreas made a minor cleanup to function gfs2_page_add_databufs.
18. Andreas got rid of function gfs2_log_header_in in preparation for
    the new log header fields.
19. Andreas also fixed up some missing newlines in kernel messages.
20. Andy Price added a new field to resource groups to indicate where
    the next one should be, to allow fsck.gfs2 to make better repairs.
21. Andy also added new rindex fields for consistency checking.
22. Andy added a crc field to resource group headers for consistency
    checking.
23. I added a patch to reduce redundancy in functions common to
    freeing dinodes.
24. I added a patch to reduce redundancy when writing log headers
    between the journalling code and journal recovery code.
25. I added a patch to add new fields to journal log headers based
    on a prototype from Steve Whitehouse.
26. I added a patch to log the source of journal log headers so we
    can better track down journal corruption.
27. I added a patch to fix a minor comment typo.
28. I also added a patch to fix a BUG in an unlink error path.
29. Steve Whitehouse contributed a patch to fix an incorrect use
    of the gfs2_blk2rgrpd function.
30. Tetsuo Handa contributed a patch that fixes incorrect error
    handling in function init_gfs2_fs.
