From 659f865ea65a60564ce00a0c571099d1fa55e8e3 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Tue, 29 Apr 2008 01:02:16 -0700 Subject: [PATCH] zorro: use non-racy method for proc entries creation Use proc_create()/proc_create_data() to make sure that ->proc_fops and ->data be setup before gluing PDE to main tree. Add correct ->owner to proc_fops to fix reading/module unloading race. Signed-off-by: Denis V. Lunev Cc: Geert Uytterhoeven Cc: Alexey Dobriyan Cc: "Eric W.
