[PATCH 2/5] xfs: add flush flag to xfs_eofblocks

To: xfs@xxxxxxxxxxx
Subject: [PATCH 2/5] xfs: add flush flag to xfs_eofblocks
From: Brian Foster <bfoster@xxxxxxxxxx>
Date: Fri, 28 Mar 2014 09:16:00 -0400
Delivered-to: xfs@xxxxxxxxxxx
In-reply-to: <1396012563-60973-1-git-send-email-bfoster@xxxxxxxxxx>
References: <1396012563-60973-1-git-send-email-bfoster@xxxxxxxxxx>
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.
