Subject: [PATCH 2/5] xfs: add flush flag to xfs_eofblocks
Date: Fri, 28 Mar 2014 09:16:00 -0400 [thread overview]
Message-ID: <1396012563-60973-3-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1396012563-60973-1-git-send-email-bfoster@redhat.com>
The flush flag allows the caller to issue a flush for scanned inodes. In
ENOSPC conditions caused by project quotas, a flush is required to free
up reserved metadata allocations.
