Hi!
From: Chengguang Xu cgxu519@mykernel.net
[ Upstream commit 909110c060f22e65756659ec6fa957ae75777e00 ]
Setting softlimit larger than hardlimit seems meaningless for disk quota but currently it is allowed. In this case, there may be a bit of comfusion for users when they run df comamnd to directory which has project quota.
For example, we set 20M softlimit and 10M hardlimit of block usage limit for project quota of test_dir(project id 123).

blocksize disappeared here. That can't be right.
Plus, is this just obfuscated way of saying
limit = min_not_zero(dquot->dq_dqb.dqb_bsoftlimit, dquot->dq_dqb.dqb_bhardlimit)?
Please skip this patch from stable list, I'll send a revised patch to upstream.
This patch is already in Linus's tree, so you can't send a "revised" version, only one that applies on top of this one :)
That being said, I'll go drop this from the stable queues, thanks. Please let us know when the fixed patch is in Linus's tree and we will be glad to take both of them.
I got it, Thanks Greg!
