Re: XFS mount option

[Eric Sandeen <sandeen@sgi.com>]

After just a quick glance, it looks like we do handle the sync option.

in xfs_write, we do:

        /* Handle various SYNC-type writes */
        if ((file->f_flags & O_SYNC) || IS_SYNC(file->f_dentry->d_inode)) {

... etc ...

and the IS_SYNC looks for the MS_SYNCHRONOUS flag on the mount, which is
set when you mount with sync.

So there's the 10,000-foot handwaving answer.  :)  You might do some
testing to see if this all really works.
