Subject: raw: Use helpers for the hlist_nulls variant.
X-Git-Tag: v6.6.17~6916^2~324^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f289c02bf41b55fbfccf21d72c4ac44cd4a7a107;p=platform%2Fkernel%2Flinux-rpi.git

raw: Use helpers for the hlist_nulls variant.

hlist_nulls_add_head_rcu() and hlist_nulls_for_each_entry() have dedicated
macros for sk.
