ceph: add F_SYNC file flag to force sync (non-O_DIRECT) io 2011-07-26T18:26:07+00:00 Sage Weil sage@newdream.net 2011-07-26T18:26:07+00:00 4918b6d140c4822201ebbe2f070875332aff337b 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>

The only real downside to allowing the user to set it is that you don't get default values by zeroing the layout struct (the default is -1). Signed-off-by: Sage Weil <sage@newdream.net>
