Package: src:linux
Version: 4.0.2-1
Severity: critical
Tags: upstream
4.0.3 includes a fix for a critical ext4 bug that can result in major
data loss. I believe this is the bug I just hit on my server, resulting
in massive filesystem corruption. See upstream commit
d2dc317d564a46dfc683978a2e5a4f91434e9711 ("ext4: fix data corruption
caused by unwritten and delayed extents"), which has been added to
stable kernels 4.0.3 as well as much older stable kernels.
Please consider incorporating this patch into the Debian kernels as soon
as possible, including into the Jessie kernel.
