Subject: [PATCH,RFC] Adding quotacheck functionality to e2fsck


This is something I whipped up last night to speed up quotacheck by
doing the data collection in e2fsck.  If e2fsck runs and does a full
check, it's likely that quotacheck needs to be run as well --- and it's
faster if e2fsck does the dirty work of fetching the information since
(1) it needs to paw through all of the inodes anyway, and (2) quotacheck
has to go through the file system and iterate over the files in an
non-optimal order.

What do folks think?  Obviously changes in quotacheck would be required
before it could take advantage of these output files, but hopefully that
shouldn't be hard...

To use, either use:

   e2fsck -E usrquota_check=/tmp/quota.user,grpquota_check=/tmp/quota.group

or you can edit /etc/e2fsck.conf and add:

[quota]
	directory = /var/e2fsck/quota

I still need to write documentation, update the man pages, and do some
polishing, so this is still in a pretty rough state, but I'd appreciate
comments.

Thanks,

     	      					- Ted
