From eafea7390e597f766927d1ba7459f3904b0b9194 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Sat, 7 Jan 2017 20:04:23 -0800 Subject: [PATCH] net: ipv4: remove disable of bottom half in inet_rtm_getroute Nothing about the route lookup requires bottom half to be disabled. Remove the local_bh_disable ... local_bh_enable around ip_route_input. This appears to be a vestige of days gone by as it has been there since the beginning of git time.
