Thanks for the quick 3rd version of quota patches on ocfs2,is this patch
set based on mark's kernel tree or mainline? i'll soon check my reported
bug on your provided kernel:)

BTW, I've worked out a first version of sanity checker for quota on
ocfs2,now its only on a single-node mode,will try to work on
mutiple-nodes tests later for node crash,heavy parallel quota usage and
negative quota usage test etc.maybe by the help of openmpi tools:)

I've attached the singe-node test script by this mail,you may have it
for sanity check if you wish,it includes one user/one group/multiple
groups test for all quota related generic functions(also soft/hard/grace
time limitaion for inodes and space usage tested here),you also can tune
the workload extremely high to expect it as a stress puncher.

it can be used like,

./quota_tests.sh -o quotalog -d /dev/sdc5 -t ocfs2 -i small /quota (here
-i specify the workload, small means for a generic test,medium and large
increase the stress sharply:)

I've tested you 2rd version of patch set by specifying a medium
workload,the result was good to me:)

The testing status and testing tools will be kept on

Tristan.
