The patch titled
cpci_hotplug: partially convert to use the kthread API
has been removed from the -mm tree. Its filename was
cpci_hotplug-partially-convert-to-use-the-kthread-api.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: cpci_hotplug: partially convert to use the kthread API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
kthread_run replaces the kernel_thread and daemonize calls during thread
startup.
Calls to signal_pending were also removed as it is currently impossible for
the cpci_hotplug thread to receive signals.
akpm: needs to be converted to kthread_should_stop() and kthread_stop().
