Subject[PATCH 4.14 175/185] ext4: fix warning inside ext4_convert_unwritten_extents_endio
Date
From: Rakesh Pandit <rakesh@tuxera.com>

commit e3d550c2c4f2f3dba469bc3c4b83d9332b4e99e1 upstream.

Really enable warning when CONFIG_EXT4_DEBUG is set and fix missing
first argument. This was introduced in commit ff95ec22cd7f ("ext4:
add warning to ext4_convert_unwritten_extents_endio") and splitting
extents inside endio would trigger it.

Fixes: ff95ec22cd7f ("ext4: add warning to ext4_convert_unwritten_extents_endio")
