[PATCH 4.18 020/197] sctp: remove useless start_fail from sctp_ht_iter in proc

From: Greg Kroah-Hartman
Date: Thu Sep 13 2018 - 09:51:16 EST


4.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Xin Long <lucien.xin@xxxxxxxxx>

[ Upstream commit 834539e69a5fe2aab33cc777ccfd4a4fcc5b9770 ]

After changing rhashtable_walk_start to return void, start_fail would
never be set other value than 0, and the checking for start_fail is
pointless, so remove it.

Fixes: 97a6ec4ac021 ("rhashtable: Change rhashtable_walk_start to return void")
