From 45128b08f74131753a10a584e3e5c4496b279269 Mon Sep 17 00:00:00 2001 From: zhong jiang Date: Fri, 17 Aug 2018 00:37:15 +0800 Subject: [PATCH] btrfs: change btrfs_pin_log_trans to return void btrfs_pin_log_trans defines the variable "ret" for return value, but it is not modified after initialization. Further, I find that none of the callers do handles the return value, so it is safe to drop the unneeded "ret" and make it return void.
