Subject: ocfs2: Remove ->hangup() from stack glue operations.
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2c39450b39880e162b3eb339672314101f58ee1a;p=openwrt%2Fstaging%2Fblogic.git

ocfs2: Remove ->hangup() from stack glue operations.

The ->hangup() call was only used to execute ocfs2_hb_ctl.  Now that
the generic stack glue code handles this, the underlying stack drivers
don't need to know about it.
