Prev: [PATCH] btrfs: set task state with schedule_timeout_uninterruptible()
Next: [PATCH] drm: nouveau: set TASK_(UN)INTERRUPTIBLE before schedule_timeout()
From: Kulikov Vasiliy on 26 Jul 2010 04:30
imx21_hc_reset() uses schedule_timeout() without setting state to
STATE_(UN)INTERRUPTIBLE. As it is called in cycle without checking of
pending signals, use schedule_timeout_uninterruptible().
