[PATCH 1/3] UEAGLE : use interruptible sleep

[matthieu castet]

Hi,


this patch use wait_event_interruptible_timeout and msleep_interruptible 
beacause uninterruptible sleep (task state 'D') is counted as 1 towards 
load average, like running processes.

use *_interruptible :
Uninterruptible sleep (task state 'D') is counted as 1 towards load average, lik
e running processes.  Interruptible sleep is not.
