From ac0ece9174aca9aa895ce0accc54f1f8ff12d117 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 3 Feb 2014 14:03:03 -0500 Subject: [PATCH] scsi: use device_remove_file_self() instead of device_schedule_callback() driver-core now supports synchrnous self-deletion of attributes and the asynchrnous removal mechanism is scheduled for removal. Use it instead of device_schedule_callback(). This makes "delete" behave synchronously. Signed-off-by: Tejun Heo Cc: "James E.J.
