Subject: [patch 24/25]  pcwd: replace schedule_timeout() with 	msleep()
Date: Wed, 01 Sep 2004 22:57:50 +0200	[thread overview]
Message-ID: <E1C2cAw-0007WP-J6@sputnik> (raw)







I would appreciate any comments from the janitor@sternweltens list. This is one (of
many) cases where I made a decision about replacing

set_current_state(TASK_INTERRUPTIBLE);
schedule_timeout(some_time);

with

msleep(jiffies_to_msecs(some_time));

msleep() is not exactly the same as the previous code, but I only did
this replacement where I thought long delays were *desired*. If this is
not the case here, then just disregard this patch.

Thanks,
Nish



Description: Uses msleep() instead of schedule_timeout() to guarantee
the task delays at least the desired time amount.
