2024-01-05bcachefs: bch_member->seqKent Overstreet
Add new fields for split brain detection: - bch_member->seq, which tracks the sequence number of the last superblock write that happened to each member device - bch_sb->write_time, which tracks the time of the last superblock write, to allow detection of when two members have diverged but had the same number of superblock writes.

2024-01-05bcachefs: Fix nochanges/read_only interactionKent Overstreet
nochanges means "we cannot issue writes at all"; it's possible to go into a pseudo read-write mode where we pin dirty metadata in memory, which is used for fsck in dry run mode and doing journal replay on a read only mount, but we do not want to allow an actual read-write mount in nochanges mode. But we do always want to allow early read-write, during recovery - this patch clarifies that. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-01-05buffer: fix unintended successful returnMatthew Wilcox (Oracle)
If try_to_free_buffers() succeeded and then folio_alloc_buffers() failed, grow_dev_folio() would return success. This would be incorrect; memory allocation failure is supposed to result in a failure. It's a harmless bug; the caller will simply go around the loop one more time and grow_dev_folio() will correctly return a failure that time. But it was an unintended change and looks like a more serious bug than it is. While I'm in here, improve the commentary about why we return success even though we failed.

2024-01-04ext4: clarify handling of unwritten bh in __ext4_block_zero_page_range()Ojaswin Mujoo
As an optimization, I was trying to work on exiting early from this function if dealing with unwritten extent since they anyways read 0. However, it was realised that there are certain code paths that can end up calling ext4_block_zero_page_range() for an unwritten bh that might still have data in pagecache. In this case, we can't exit early and we do require to process the bh and zero out the pagecache to ensure that a writeback can't kick in at a later time and flush the stale pagecache to disk. Since, adding the logic to exit early for unwritten bh was turning out to be much more nuanced and the current code already handles it well, just add a comment to explicitly document this behavior.

2024-01-04nfsd: drop the nfsd_put helperJeff Layton
It's not safe to call nfsd_put once nfsd_last_thread has been called, as that function will zero out the nn->nfsd_serv pointer. Drop the nfsd_put helper altogether and open-code the svc_put in its callers instead. That allows us to not be reliant on the value of that pointer when handling an error.
