Subject[PATCH 4.19 102/243] f2fs: fix to account preflush command for noflush_merge mode
Date
From: Chao Yu <yuchao0@huawei.com>

[ Upstream commit a8075dc484cf10ebdb07bee2b17322fb0a846309 ]

Previously, we only account preflush command for flush_merge mode,
so for noflush_merge mode, we can not know in-flight preflush
command count, fix it.
