Subject: [PATCH AUTOSEL 4.19 17/26] f2fs: handle unallocated section and zone on pinned/atgc
Date: Wed, 24 Feb 2021 07:54:25 -0500 [thread overview]
Message-ID: <20210224125435.483539-17-sashal@kernel.org> (raw)
In-Reply-To: <20210224125435.483539-1-sashal@kernel.org>
From: Jaegeuk Kim <jaegeuk@kernel.org>
[ Upstream commit 632faca72938f9f63049e48a8c438913828ac7a9 ]
If we have large section/zone, unallocated segment makes them corrupted.
E.g.,
- Pinned file: -1 119304647 119304647
- ATGC data: -1 119304647 119304647
