From dc37910d4c63296513c5795187d020ad9793822b Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 19 Feb 2019 17:08:18 +0800 Subject: f2fs: make fault injection covering __submit_flush_wait() This patch changes to allow failure of f2fs_bio_alloc() in __submit_flush_wait(), which can simulate flush error in checkpoint() for covering more error paths.
