From a973909fc32be90884280b7a8cd2f2e093c97890 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Tue, 29 Apr 2008 01:02:17 -0700 Subject: scsi: use non-racy method for proc entries creation Use proc_create() to make sure that ->proc_fops 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: Greg Kroah-Hartman Cc: Alexey Dobriyan Cc: "Eric W.
