Subject: [PATCH 0/2] Make HWPoison helpers config-independent
Date: Thu, 3 Sep 2026 13:35:33 +0800 [thread overview]
Message-ID: <20260903053535.17611-1-kaitao.cheng@linux.dev> (raw)
Make the HWPoison page flag's test-and-set and test-and-clear accessors
available regardless of CONFIG_MEMORY_FAILURE. When memory failure handling
is disabled, the accessors return false, matching the absence of HWPoison
state and providing a consistent interface across configurations.
Use the config-independent interface in the pmem driver to remove its
private test_and_clear_pmem_poison() wrapper and the associated header
dependency. No functional change is intended.
