Subject: [PATCH kdevops] xfs: update expunges with two new crashes one related to btrfs sparse files
Date: Thu, 11 Apr 2024 16:47:42 -0700	[thread overview]
Message-ID: <20240411234743.3464688-1-mcgrof@kernel.org> (raw)

One is already known, the other one seems new, and it is triggerable
by using sparse files on a btrfs partition for testing xfs on test
generic/476 (no SOAK_DURATION needed), so the bug is specific to btrfs.
The bug is triggered on the btrfs-endio-write btrfs_work_helper
workqueue and hits BUG_ON() on a dad page state on the call
btrfs_release_extent_buffer_pages() [0].

We've done extensive testing of XFS on v6.6-rc5 and recently we moved
to v6.8, and so this could be an issue introduced on v6.7 or v6.8.

This is a kdevops specific expunge patch, but I figured btrfs folks
would be interested about hearing about this btrfs crash. Hopefully the
above sumarizes enough to enable to folks who may want to reproduce to
give it a shot. I am not yet sure of the failure rate as I just ran into
it on my first shot on v6.8.

A fix for the xfs specifically triggered fsstress + compaction crash is
already on my radar but documenting it for posterity.
