Hmm, the filesystem went down...

...and I think this is complaining about this debugging test in
iomap_page_release:

	WARN_ON_ONCE(bitmap_full(iop->uptodate, nr_blocks) !=
			folio_test_uptodate(folio));

which checks that we're not releasing or invalidating a page that's
partially uptodate on a blocksize < pagesize filesystem (or so I gather
from "POWER10 LPAR" (64k pages?) and "XFS" (4k blocks?))...

...but in this particular case, we're dumping pages (and inodes) as part
of unmounting the filesystem, in which case we've already flushed dirty
data to disk, because sync_filesystem gets called before evict_inodes
here...

...aha!  The filesystem has gone down (hence the metadata IO errors at
the top of the report) during generic/475, which is a test that
exercises filesystem crash recovery.  It simulates a crash by calling
EXT4_IOC_SHUTDOWN and unmounting.

Given that in this case we've already cleared SB_ACTIVE from the
superblock s_flags, I wonder if we could amend that code to read:

	if (inode->i_sb->s_flags & SB_ACTIVE)
		WARN_ON_ONCE(bitmap_full(iop->uptodate, nr_blocks) !=
				folio_test_uptodate(folio));

Since we don't really care about memory pages that aren't fully up to
date if we're in the midst of freeing all the incore filesystem state.

Thoughts?

Ooh, nice! :)

It's been there since the start of fs/iomap, so bisecting wouldn't help
much anyway.
