From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Benjamin Marzinski Date: Thu, 14 Jan 2021 20:20:26 -0600 Subject: [PATCH] multipathd: combine free_io_err_stat_path and destroy_directio_ctx destroy_directio_ctx() is only called from free_io_err_stat_path(), and free_io_err_stat_path() is very short, so combine them.
