Subject: rtems-yaffs: Checkpoint the filesystem at unmount time
X-Git-Url: https://yaffs.net/gitweb/?p=yaffs2.git;a=commitdiff_plain;h=8921e0e0ebe4265c5549a790e166c54a826ad512

rtems-yaffs: Checkpoint the filesystem at unmount time

Adding a checkpoint greatly reduces the amount of time required to mount
the filesystem on the next boot.  After a clean unmount, remount time
is only a second or few.  After an unclean reboot, remount time requires
a scan of the filesystem, which can take a few minutes.
