Check for partially applied patch.


Thanks Kostik. You can double check me on sizes, but it would appear that
all files in the patch were touched, and I double checked my sources with:
ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/6.2-RELEASE/src which are
The patch is against RELENG_6, not against RELENG_6_2. I see no point
in backporting it to RELENG_6_2.

BTW, I backported two fixes, one for another deadlock with snapshots and
quotas, another for "ffs_blkfree: block already freed" panic and followed
up fsck: softdep inconsistency error.

New combined patch (against RELENG_6) is at
http://people.freebsd.org/~kib/quotagiant/quotas-RELENG_6-20080221-1202.patch

I tried to apply this patch to recent RELENG_6 sources
but it failed at a lot of places. I think this is due to
changes to the tree after the above patch was made.

Is there any newer patch available or is it possible to make
one which applies to recent RELENG_6 sources?

I have this patch now running on a

CPU: Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz (3001.18-MHz 686-class CPU)

machine. I have attached two 10k SCSI drives to an AIC7902
controller. These two drives have quotas enabled and are
constantly copying 77GB of data stored in ~210000 files to
each other. I use about 75 different user and group IDs with
these files.

I haven't had any problem the last 6 hours. The machine runs
rocksolid and the quota values are correct. So, from my point
of view I'd say that the patch works great!

Thanks a lot for the nice work,

-Andre
