From 1f473e9c92ea458e60494561a2065a358b7239bb Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 29 Dec 2008 20:27:29 +0100 Subject: ide: IDE settings don't need an ide_lock held IDE settings are protected by ide_setting_mtx mutex so there is no need to hold ide_lock in ide_setting_ioctl(), ide_read_setting() and ide_proc_unregister_driver().
