async is the other extreme end of the spectrum from sync..

async   All I/O to the file system should be done asynchronously.
                     This is a dangerous flag to set, and should not be used
                     unless you are prepared to recreate the file system
                     should your system crash.

noasync
                     Metadata I/O should be done synchronously, while data I/O
                     should be done asynchronously.  This is the default.

sync    	     All I/O to the file system should be done synchronously.
