Subject: [f2fs-dev] [PATCH 2/2] f2fs: avoid to select pinned section during checkpoint=disable
Date: Tue,  3 May 2022 13:30:40 -0700	[thread overview]
Message-ID: <20220503203040.365028-2-jaegeuk@kernel.org> (raw)
In-Reply-To: <20220503203040.365028-1-jaegeuk@kernel.org>

The f2fs_gc uses a bitmap to indicate pinned sections, but when disabling
chckpoint, we call f2fs_gc() with NULL_SEGNO which selects the same dirty
segment as a victim all the time, resulting in checkpoint=disable failure.
Let's pick another one, if we fail to collect it.
