Subject: [f2fs-dev] [PATCH 1/2] f2fs: remove unused GC_FAILURE_PIN
Date: Mon, 6 May 2024 18:45:37 +0800 [thread overview]
Message-ID: <20240506104538.778116-1-chao@kernel.org> (raw)
After commit 3db1de0e582c ("f2fs: change the current atomic write way"),
we removed all GC_FAILURE_ATOMIC usage, let's change i_gc_failures[]
array to i_pin_failure for cleanup.
Meanwhile, let's define i_current_depth and i_gc_failures as union
variable due to they won't be valid at the same time.
