Subject: [NET] napi: use non-interruptible sleep in napi_disable
X-Git-Tag: v2.6.24-rc2~132^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=43cc7380eced27ee9cafdf89fa32333dc3884e8b;p=profile%2Fivi%2Fkernel-x86-ivi.git

[NET] napi: use non-interruptible sleep in napi_disable

The current napi_disable() uses msleep_interruptible() but doesn't
(and can't) exit in case there's a signal, thus ending up doing a
hot spin without a cpu_relax. Use uninterruptible sleep instead.
