Subject: UEAGLE : use interruptible sleep
X-Git-Tag: v2.6.19-rc3~137^2~36
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=531a39bbab213209a9914e68809bcf8b60a54f47;p=~emulex%2Finfiniband.git

UEAGLE : use interruptible sleep

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.
