Merge tag 'gfs2-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull GFS2 updates from Andreas Gruenbacher:
"Bob's extensive filesystem withdrawal and recovery testing:
- don't write log headers after file system withdraw
- clean up iopen glock mess in gfs2_create_inode
- close timing window with GLF_INVALIDATE_IN_PROGRESS
- abort gfs2_freeze if io error is seen
- don't loop forever in gfs2_freeze if withdrawn
- fix infinite loop in gfs2_ail1_flush on io error
- introduce function gfs2_withdrawn
- fix glock reference problem in gfs2_trans_remove_revoke
Filesystems with a block size smaller than the page size:
- fix end-of-file handling in gfs2_page_mkwrite
- improve mmap write vs. punch_hole consistency
Other:
- remove active journal side effect from gfs2_write_log_header
- multi-block allocations in gfs2_page_mkwrite
Minor cleanups and coding style fixes:
- remove duplicate call from gfs2_create_inode
- make gfs2_log_shutdown static
- make gfs2_fs_parameters static
- some whitespace cleanups
- removed unnecessary semicolon"
