Hi,
I am unable to recreate the failure reported above. I am using xfsprogs v6.9.0
and Linux kernel v6.11-rc6 on my test system.
I am using a test environment created by Kdevops. However, I have made sure
that SCRATCH_XFS_LIST_METADATA_FIELDS and SCRATCH_XFS_LIST_FUZZ_VERBS are set
to values mentioned in the above bug report.
# uname -r
6.11.0-rc6
# xfs_repair -V
xfs_repair version 6.9.0
# ./naggy-check.sh --section xfs_reflink_modified -c 1 xfs/556
SCRATCH_XFS_LIST_METADATA_FIELDS = u3.sfdir3.hdr.parent.i4
SCRATCH_XFS_LIST_FUZZ_VERBS = random
SECTION -- xfs_reflink_modified
RECREATING -- xfs on /dev/loop16
FSTYP -- xfs (debug)
PLATFORM -- Linux/x86_64 xfs-reflink 6.11.0-rc6 #2 SMP PREEMPT_DYNAMIC Tue Sep 3 09:34:50 GMT 2024
MKFS_OPTIONS -- -f /dev/loop5
MOUNT_OPTIONS -- -o context=system_u:object_r:root_t:s0 /dev/loop5 /media/scratch
xfs/556 6s ... 5s

SECTION -- xfs_reflink_modified
=========================
Ran: xfs/556
Passed all 1 tests
naggy-check.sh is a wrapper around xfstests' "check" script. I have modified
it to print the values of the environment variables
SCRATCH_XFS_LIST_METADATA_FIELDS and SCRATCH_XFS_LIST_FUZZ_VERBS.
