Summary: [xfstests generic/648] BUG: unable to handle page
fault, RIP: 0010:__xfs_dir3_data_check+0x171/0x700
[xfs]
Product: File System
Version: 2.5
Kernel Version: v6.1-rc0
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: XFS
Assignee: filesystem_xfs@kernel-bugs.kernel.org
Reporter: zlang@redhat.com
Regression: No
xfstests generic/648 hit kernel panic[1] on xfs with 64k directory block size
(-n size=65536), before panic, there's a kernel assertion (not sure if it's
related).
It's reproducable, but not easy. Generally I reproduced it by loop running
generic/648 on xfs (-n size=65536) hundreds of time.
The last time I hit this panic on linux with HEAD=

Given that there have been no changes to XFS committed in v6.1-rc0
at this point in time, this won't be an XFS regression unless you
can reproduce it on 6.0 or 5.19 kernels, too. Regardless, I'd suggest
bisection is in order to find where the problem was introduced.

It's not a regression recently, I even can reproduce it on RHEL-9 (which base
on 5.14 kernel).
