Subject: [PATCH v2] f2fs: turn back remapped address in compressed page endio
Date: Wed, 28 Jul 2021 12:38:11 -0700	[thread overview]
Message-ID: <20210728193811.2519412-1-daeho43@gmail.com> (raw)

From: Daeho Jeong <daehojeong@google.com>

Turned back the remmaped sector address to the address in the partition,
when ending io, for compress cache to work properly.

Fixes: 6ce19aff0b8c ("f2fs: compress: add compress_inode to cache
compressed blocks")
