Subject: net/mac80211,rcu: convert call_rcu(work_free_rcu) to kfree_rcu()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a74ce1425e4f6075de443274a5e917c84357eac4;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

net/mac80211,rcu: convert call_rcu(work_free_rcu) to kfree_rcu()

The rcu callback work_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(work_free_rcu).
