hi,
   Here is one possible solution for achieving this: \
http://review.gluster.org/#change,4280. The solution posted achieves it by pausing \
flush/fsync fop until the delayed post-op is completed. Writevs are unwound only \
after its post-op is marked for delay. This prevents the race of flush not witnessing \
delayed post-op in fd-ctx. The problem is that the solution is ugly. I am wondering \
if you guys have other solutions to achieve the same without making flush/fsync a \
transaction.

Pranith.
