Subject: [PATCH 0/3] xfs: change available ranges in quota check
Date: Mon, 23 Jan 2012 12:45:14 +0900 [thread overview]
Message-ID: <20120123034513.3339.97432.stgit@ltc219.sdl.hitachi.co.jp> (raw)
Hi,
This patch series changes available ranges of softlimit and
hardlimit in quota check, as follows.
(1) Consider new reservation for quota check
The disk block reservation checks if (current usage + new
reservation) reach the quota limit although the inode reservation
does not use the new reservation for quota check. It should
consider it, as well. This is mandatory for (2).
(2) Change available ranges of softlimit and hardlimit in quota check
Currently xfs quota allows us to use disk blocks and inodes
up to lower than quota limits. They should be used up to
not greater than the limits.
Thanks,
---
