Subject: [Bug 201685] ext4 file system corruption
Date: Mon, 03 Dec 2018 16:20:41 +0000 [thread overview]
Message-ID: <bug-201685-13602-0ahI3Sw8af@https.bugzilla.kernel.org/> (raw)
In-Reply-To: <bug-201685-13602@https.bugzilla.kernel.org/>
https://bugzilla.kernel.org/show_bug.cgi?id=201685
--- Comment #204 from Guenter Roeck (linux@roeck-us.net) ---
Another update:
Still working on a reliable reproducer. I have been able to reproduce the
problem again with v4.19.6 and the following patches reverted.
Revert "ext4: handle layout changes to pinned DAX mappings"
Revert "dax: remove VM_MIXEDMAP for fsdax and device dax"
Revert "ext4: close race between direct IO and ext4_break_layouts()"
I used a modified version of #185, running on each drive on the affected
system, plus a kernel build running in parallel.
