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window with GLF_INVALIDATE_IN_PROGRESS - abort gfs2_freeze if io error is seen - don't loop forever in gfs2_freeze if withdrawn - fix infinite loop in gfs2_ail1_flush on io error - introduce function gfs2_withdrawn - fix glock reference problem in gfs2_trans_remove_revoke Filesystems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" * tag 'gfs2-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: gfs2: Don't write log headers after file system withdraw gfs2: Remove duplicate call from gfs2_create_inode gfs2: clean up iopen glock mess in gfs2_create_inode gfs2: Close timing window with GLF_INVALIDATE_IN_PROGRESS gfs2: Abort gfs2_freeze if io error is seen gfs2: Don't loop forever in gfs2_freeze if withdrawn gfs2: fix infinite loop in gfs2_ail1_flush on io error gfs2: Introduce function gfs2_withdrawn gfs2: fix glock reference problem in gfs2_trans_remove_revoke gfs2: make gfs2_log_shutdown static gfs2: Remove active journal side effect from gfs2_write_log_header gfs2: Fix end-of-file handling in gfs2_page_mkwrite gfs2: Multi-block allocations in gfs2_page_mkwrite gfs2: Improve mmap write vs. punch_hole consistency gfs2: make gfs2_fs_parameters static gfs2: Some whitespace cleanups gfs2: removed unnecessary semicolon
