Please consider replacing with the following patch (just a minor change):

Description: Use msleep() instead of schedule_timeout() to guarantee the
task delays as expected. Remove set_current_state() as it is taken care of by
msleep().

This patch should be dropped. The msleep() call will ignore waitqueue events
set up by prepare_to_wait().

Please consider replacing with the following patch:

Description: Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. TASK_INTERRUPTIBLE is used currently, however signals /
early returns from schedule_timeout() are not checked for. Thus msleep() is more
appropriate.

> msleep_interruptible-drivers_base_dmapool.patch

Please replace with the following patch. msleep_interruptible() is not
appropriate for this delay, as the waitqueue events will be missed.
TASK_UNINTERRUPTIBLE should be used instead of TASK_INTERRUPTIBLE, though, as
signals are not checked for.

Please consider replacing with the following patch:

Description: Use msleep() instead of pf_sleep() to guarantee
the task delays as expected. TASK_INTERRUPTIBLE is used in the original code,
however there is no check on the return values / for signals, thus I believe
TASK_UNINTERRUPTIBLE (and hence msleep()) is more appropriate. Remove the

These two patches are combined in the following, please replace.

Description: Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Although TASK_INTERRUPTIBLE is used in the original code,
the schedule_timeout() return conditions for such a state are not checked
appropriately; therefore, TASK_UNINTERRUPTIBLE should be ok (and, hence,
msleep()).

Please consider replacing with the following:

Description: Use ssleep() instead of nicedelay()
to guarantee the task delays as expected. Remove the prototype and
definition of nicedelay(). This is a very weird function, because it is
called to sleep in terms of usecs, but always sleeps for 1 second,
completely ignoring the parameter. I have gone ahead and followed suit,
just sleeping for a second in all cases, but maybe someone with the
hardware could tell me if perhaps the paramter *should* matter. Additionally,
nicedelay() is called in TASK_INTERRUPTIBLE state, but doesn't deal with signals
in case these longer delays do not complete, so I believe ssleep() is more
appropriate.

Please consider replacing with the following patch:

Description: Use msleep()/ssleep() instead of pg_sleep() to guarantee
the task delays as expected. TASK_INTERRUPTIBLE is used in the original code,
however there is no check on the return values / for signals, thus I believe
TASK_UNINTERRUPTIBLE (and hence msleep()) is more appropriate. Change pg_sleep()
to use TASK_UNINTERRUPTIBLE as well.

Consider replacing with the following patch, as signals are not dealt with in
the existing code:

Description: Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Although TASK_INTERRUPTIBLE is used in the current code,
there is no code dealing with an early return / signals_pending().

Please drop this patch, as it incorrectly uses msleep() around waitqueues.

Your conversion of nicedelay() -> ssleep() values is imprecise.

The author clearly intended the values to be different, right?

True, but this is what I attempted to allude to in the description of the patch:

Since I'm not the author, I'm not certain whether you are right or
not. I was honestly very confused by nicedelay(). It is called with
various 600000, 500000, 200000 usecs, but the function currently
always requests a 1000000 usec delay (a full second of interruptible
sleep). It just doesn't make any sense... I have sent messages
regarding this function several times (and patches have existed for a
while), but no one has had any comment. I appreciate your input
greatly. What do you think?

Thanks,
Nish
