[Ocfs2-devel] [PATCH 03/30] ocfs2: Handle workqueue changes

Sunil Mushran sunil.mushran at oracle.com
Thu Dec 20 15:29:20 PST 2007


Commit 52bad64d95bd89e08c49ec5a071fa6dcbe5a1a9c in mainline makes
changes to workqueue.h. This patch allows one to build ocfs2 with
kernels having/not having that change.
