Jaroslav, I realize that you are not the explicit maintainer for many of
these drivers, but I figured you would at least be able to {N,}ACK the
changes. I tried to add any Maintainers I could find to the recipient
list, and hope any I missed are on one of the two lists. I'm sorry for
having put them into the same patchset, and if split patches would be
preferred, I can do that.
Description: Fix-up sleeping in sound/pci. These changes fall under the
following two categories:
1) Replace schedule_timeout() with msleep() to guarantee the
task delays as expected. This also involved replacing/removing
custom sleep functions.
2) Do not assume jiffies will only increment by one if you
request a 1 jiffy sleep, i.e. use time_after/time_before in
while loops.
Patch is compile-tested.

From: Nishanth Aravamudan <nacc@us.ibm.com>
Jaroslav, I realize that you are not the explicit maintainer for many of
these drivers, but I figured you would at least be able to {N,}ACK the
changes. I tried to add any Maintainers I could find to the recipient
list, and hope any I missed are on one of the two lists. I'm sorry for
having put them into the same patchset, and if split patches would be
preferred, I can do that.
Description: Fix-up sleeping in sound/pci. These changes fall under the
following two categories:
1) Replace schedule_timeout() with msleep() to guarantee the
task delays as expected. This also involved replacing/removing
custom sleep functions.
2) Do not assume jiffies will only increment by one if you
request a 1 jiffy sleep, i.e. use time_after/time_before in
while loops.
Patch is compile-tested.

Patch is compile-tested.

^ permalink raw reply [flat|nested] 29+ messages in thread* [PATCH 3/14] sound/usb: fix-up sleeping paths
@ 2005-07-09 0:04 ` Nishanth Aravamudan
0 siblings, 0 replies; 29+ messages in thread
From: Nishanth Aravamudan @ 2005-07-09 0:04 UTC (permalink / raw)
To: perex; +Cc: alsa-devel, linux-sound
From: Nishanth Aravamudan <nacc@us.ibm.com>
Jaroslav, I realize that you are not the explicit maintainer for any of
these drivers, but I figured you would at least be able to {N,}ACK the
changes. I didn't find any entry in MAINTAINERS for usb-specific sound
drivers. If you would prefer split patches instead of the large
patchset, I can do that.
Description: Fix-up sleeping in sound/usb. Replace big_mdelay() with
msleep() to guarantee the task delays as expected. This also involved
replacing/removing custom sleep functions.
Patch is compile-tested.

From: Nishanth Aravamudan <nacc@us.ibm.com>
Description: Replace schedule_timeout() with
msleep()/msleep_interruptible() as appropriate, to guarantee the task
delays as expected.
Patch is compile-tested.
