Subject: [PATCH v5 09/10] xfs: add minimum file size filtering to eofblocks scan
Date: Fri,  5 Oct 2012 10:17:15 -0400	[thread overview]
Message-ID: <1349446636-8611-10-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1349446636-8611-1-git-send-email-bfoster@redhat.com>

Support minimum file size filtering in the eofblocks scan. The
caller must set the XFS_EOF_FLAGS_MINFILESIZE flags bit and minimum
file size value in bytes.
