The patch titled
kernel: use non-racy method for proc entries creation
has been removed from the -mm tree. Its filename was
kernel-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: kernel: 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.
