Subject: [PATCH] fsync on unmounting root
Date: Thu, 04 Jan 2001 13:47:59 -0500 [thread overview]
Message-ID: <99660000.978634079@tiny> (raw)

Looks like the prerelease, and at least test13 don't fsync the device when
someone does an unmount on /
mount -o remount works, just unmounting the root misses the fsync.
This patch works for me:
