[Kernel-janitors] [PATCH 2.6.9-rc2 3/40] net/airo: replace

Any comments would be appreciated.

Description: Use msleep()/msleep_interruptible() [as appropriate]
instead of schedule_timeout() to guarantee the task delays as
expected. Also uses set_current_state() instead of direct assignment of
current->state in one place.
