The patch titled
ocfs2: new export ops
has been removed from the -mm tree. Its filename was
ocfs2-new-export-ops.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ocfs2: new export ops
From: Christoph Hellwig <hch@xxxxxx>
OCFS2 has it's own 64bit-firendly filehandle format so we can't use the
generic helpers here. I'll add a struct for the types later.
