From 1262cc70fa42cc8d73f6bf21fcd4225ff884b713 Mon Sep 17 00:00:00 2001 From: Zorro Lang Date: Wed, 24 May 2017 22:52:58 +0800 Subject: [PATCH] xfs/196: fallback to fail_writes for old kernel linux XFS rename all "fail_writes" references to "drop_writes" in v4.11. Some old kernel still use the name "fail_writes", e.g. RHEL-7. For testing on old kernel, we need to fallback to "fail_writes".
