From 684ca7e55de1f3defb13c491e0b5eb8f27ffe79c Mon Sep 17 00:00:00 2001 From: Kinglong Mee Date: Sat, 18 Mar 2017 09:20:55 +0800 Subject: [PATCH] f2fs: avoid stat_inc_atomic_write for non-atomic file After filemap_write_and_wait_range fail, the FI_ATOMIC_FILE flags is removed, so that f2fs should not increase the stat of atomic_write.
