Subject: [PATCH v9 05/28] xfs: Hold inode locks in xfs_ialloc
Date: Wed, 26 Sep 2018 03:14:44 -0700 [thread overview]
Message-ID: <1537956907-10244-6-git-send-email-allison.henderson@oracle.com> (raw)
In-Reply-To: <1537956907-10244-1-git-send-email-allison.henderson@oracle.com>
Modify xfs_ialloc to hold locks after return. Caller
will be responsible for manual unlock. We will need
this later to hold locks across parent pointer operations
