Subject: macintosh/mediabay: convert to kthread API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
This patch modifies the startup of the media_bay_task to use kthread_run
and not a combination of kernel_thread, deamonize and sigfillset.
In addition since we now always want to ignore signals the
MB_IGNORE_SIGNALS define is removed along with the test for signal_pending.
The result is slightly simpler code that is more
maintainable.
