Subject: GPF in aio_migratepage
Date: Mon, 25 Nov 2013 22:26:45 -0500 [thread overview]
Message-ID: <20131126032645.GA32301@redhat.com> (raw)
Hi Kent,
I hit the GPF below on a tree based on 8e45099e029bb6b369b27d8d4920db8caff5ecce
which has your commit e34ecee2ae791df674dfb466ce40692ca6218e43
("aio: Fix a trinity splat"). Is this another path your patch missed, or
a completely different bug to what you were chasing ?
Dave
