Hello,

I have a server running which sometimes gets very busy. The
running application issues lots of fsync() calls. If it gets
very busy, it sometimes is not as fast as required. I
believe that most of the time is spent in processing fsync()
(commit journal, etc.). In such a situation, I'd like to
switch off all fsync()s and risk data loss instead of hours
of processing time, which in my case is more important.

Is implementing such a feature possible? It may be used as
follows:

mount /partition -o remount,disableFsync

and undone as follows:

mount /partition -o remount,enableFsync
