Subject: [PATCH 0/2] xfs: fix eof zeroing i_size race
Date: Mon, 28 Sep 2015 14:37:59 -0400	[thread overview]
Message-ID: <1443465481-63460-1-git-send-email-bfoster@redhat.com> (raw)

Hi all,

This addresses an EOF zeroing race that's been reproduced by a somewhat
obscure virtual machine workload on qcow2 vdisks with an increasing
i_size. Patch 1 contains the fix and patch 2 just adds a tracepoint that
helped identify the problem. Thoughts, reviews, flames appreciated.

Brian
