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.

xfs: always drain dio before extending aio write submission
xfs: add an xfs_zero_eof() tracepoint
