Subject: net: do not call sock_put() on TIMEWAIT sockets
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=80ad1d61e72d626e30ebe8529a0455e660ca4693;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net: do not call sock_put() on TIMEWAIT sockets

commit 3ab5aee7fe84 ("net: Convert TCP & DCCP hash tables to use RCU /
hlist_nulls") incorrectly used sock_put() on TIMEWAIT sockets.

We should instead use inet_twsk_put()
