From 6e07902f56fae81036ebc5a0b61d5ffdd739e4bc Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sat, 16 Feb 2019 08:19:55 +0000 Subject: [PATCH] net: sched: using kfree_rcu() to simplify the code The callback function of call_rcu() just calls a kfree(), so we can use kfree_rcu() instead of call_rcu() + callback function.
