The patch titled netdev: use non-racy method for proc entries creation has been removed from the -mm tree. Its filename was netdev-use-non-racy-method-for-proc-entries-creation.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: netdev: use non-racy method for proc entries creation From: "Denis V. Lunev" <den@xxxxxxxxxx> Use proc_create()/proc_create_data() to make sure that ->proc_fops and ->data be setup before gluing PDE to main tree. Signed-off-by: Denis V.
