Merge tag 'gfs2-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull gfs2 updates from Bob Peterson: "We've got a lot of patches (39) for this merge window. Most of these patches are related to corruption that occurs when journals are replayed. For example: 1. A node fails while writing to the file system. 2. Other nodes use the metadata that was once used by the failed node. 3. When the node returns to the cluster, its journal is replayed, but the older metadata blocks overwrite the changes from step 2. Summary: - Fixed the recovery sequence to prevent corruption during journal replay. - Many bug fixes found during recovery testing. - New improved file system withdraw sequence. - Fixed how resource group buffers are managed. - Fixed how metadata revokes are tracked and written. - Improve processing of IO errors hit by daemons like logd and quotad. - Improved error checking in metadata writes. - Fixed how qadata quota data structures are managed" * tag 'gfs2-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: (39 commits) gfs2: Fix oversight in gfs2_ail1_flush gfs2: change from write to read lock for sd_log_flush_lock in journal replay gfs2: instrumentation wrt ail1 stuck gfs2: don't lock sd_log_flush_lock in try_rgrp_unlink gfs2: Remove unnecessary gfs2_qa_{get,put} pairs gfs2: Split gfs2_rsqa_delete into gfs2_rs_delete and gfs2_qa_put gfs2: Change inode qa_data to allow multiple users gfs2: eliminate gfs2_rsqa_alloc in favor of gfs2_qa_alloc gfs2: Switch to list_{first,last}_entry gfs2: Clean up inode initialization and teardown gfs2: Additional information when gfs2_ail1_flush withdraws gfs2: leaf_dealloc needs to allocate one more revoke gfs2: allow journal replay to hold sd_log_flush_lock gfs2: don't allow releasepage to free bd still used for revokes gfs2: flesh out delayed withdraw for gfs2_log_flush gfs2: Do proper error checking for go_sync family of glops functions gfs2: Don't demote a glock until its revokes are written gfs2: drain the ail2 list after io errors gfs2: Withdraw in gfs2_ail1_flush if write_cache_pages fails gfs2: Do log_flush in gfs2_ail_empty_gl even if ail list is empty ...
