------------------------------------------------------
Subject: mtd_blkdevs: partially convert to use the kthread API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
kthread_run is used intead of kernel_thread, daemonize, and mucking around
blocking signals directly.
akpm: needs to be converted to kthread_should_stop() and kthread_stop(), too.
