ceph: add F_SYNC file flag to force sync (non-O_DIRECT) io
This allows us to force IO through the sync path which you normally only get when multiple clients are reading/writing to the same file or by mounting with -o sync. Among other things, this lets test programs verify correctness with a single mount. Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
