From: Eric W. Biederman <[EMAIL PROTECTED]>
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.
