This commit (100ccd18bb41 in linux-next 20240104) is bad for me.  After
it, running xfstests gives me first a bunch of errors along these lines:

00004 depmod: ERROR: failed to load symbols from /lib/modules/6.7.0-rc7-00037-g100ccd18bb41/kernel/fs/gfs2/gfs2.ko: Exec format error
00004 depmod: ERROR: failed to load symbols from /lib/modules/6.7.0-rc7-00037-g100ccd18bb41/kernel/fs/zonefs/zonefs.ko: Exec format error
00004 depmod: ERROR: failed to load symbols from /lib/modules/6.7.0-rc7-00037-g100ccd18bb41/kernel/security/keys/encrypted-keys/encrypted-keys.ko: Exec format error

and then later:

00016 generic/001       run fstests generic/001 at 2024-01-05 04:50:46
00017 [not run] this test requires a valid $TEST_DEV
00017 generic/002       run fstests generic/002 at 2024-01-05 04:50:46
00017 [not run] this test requires a valid $TEST_DEV
00017 generic/003       run fstests generic/003 at 2024-01-05 04:50:47
00018 [not run] this test requires a valid $SCRATCH_DEV
...

so I think that's page cache corruption of some kind.
