RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
xfstests generic/448 fails on XFS, it tests negative SEEK_HOLE/SEEK_DATA offset.  Ext4 has fixed this bug on bug 1494423. Then upstream found and fixed this bug later. I think below patch maybe help.

commit d6ab17f261919d212ec0a9e33d01f46df0ec1fde
Author: Darrick J. Wong <darrick.wong>

    vfs: in iomap seek_{hole,data}, return -ENXIO for negative offsets

Version-Release number of selected component (if applicable):
kernel-4.11.0-42.el7a

How reproducible:
100%

Steps to Reproduce:
run xfstests generic/448 on XFS

Actual results:
# cat results/generic/448.full 
File system magic#: 0x58465342
Allocation size: 4096

18. Test file with negative SEEK_{HOLE,DATA} offsets  
18.01 SEEK_HOLE expected -1 or -1, got 0.                         FAIL
18.02 SEEK_DATA expected -1 with errno -6, got -1.                FAIL

seek sanity check failed!

Expected results:
Test pass

Additional info:
This bug is not so urgent, and Pegas-1.0 is goint to be released, so I think fix it on "rhel-7.5-alt" is fine. Feel feel to change it to pages-1.0 if devel would like to do that.
