From 685a015e44dcd4db50ada60a9a2806659c165d9e Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Fri, 17 Jul 2015 10:52:48 +0200 Subject: [PATCH] rhashtable: Allow other tasks to be scheduled in large lookup loops Depending on system speed, the large lookup/insert/delete loops of the testsuite can take a considerable amount of time to complete causing watchdog warnings to appear. Allow other tasks to be scheduled throughout the loops. Reported-by: Meelis Roos Signed-off-by: Thomas Graf Acked-by: Eric Dumazet Signed-off-by: David S.
