From 632a9f3acd6687376cbb0b178df6048e19cbacc9 Mon Sep 17 00:00:00 2001 From: Chengguang Xu Date: Tue, 30 Apr 2019 14:40:10 +0800 Subject: quota: check time limit when back out space/inode change When we fail from allocating inode/space, we back out the change we already did. In a special case which has exceeded soft limit by the change, we should also check time limit and reset it properly.
