From 43cc7380eced27ee9cafdf89fa32333dc3884e8b Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 26 Oct 2007 04:23:22 -0700 Subject: [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. Signed-off-by: Benjamin Herrenschmidt Acked-by: Jeff Garzik Signed-off-by: David S.
