Subject: [PATCH] xfs: check if reserved free disk blocks is needed
Date: Sun,  5 Apr 2020 17:17:19 +0800	[thread overview]
Message-ID: <1586078239-14289-1-git-send-email-kaixuxia@tencent.com> (raw)

From: Kaixu Xia <kaixuxia@tencent.com>

We don't need to create the new quota inodes from disk when
they exist already, so add check if reserved free disk blocks
is needed in xfs_trans_alloc().
