Subject: kernel BUG at mm/filemap.c:238! (4.4.0-rc4)
Date: Mon, 7 Dec 2015 12:40:47 +0100 [thread overview]
Message-ID: <5665703F.4090302@redhat.com> (raw)
Hi,
"ADSP018" test from LTP[1] is triggering BUG_ON below reliably for me on 4.4.0-rc4.
I'll start a bisect - if someone already sees a suspect/culprit that could narrow
it down, please let me know.
