31807483d3952059d395c2a73b1fa9625db9b366 - mm/memory-failure: remove the selection of RAS

Wed, 19 Nov 2025 09:59:43 +0000

mm/memory-failure: remove the selection of RAScommit 97f0b13452198290799f ("tracing: add trace event formemory-failure") introduces the selection of RAS in memory-failure. Thiscommit is just a tracing feature; in reality, there is no dependencybetween memory-failure and RAS. RAS increases the size of the bzImageimage by 8k, which is very valuable for embedded devices.Move the memory-failure traceing code from ras_event.h tomemory-failure.h and remove the selection of RAS.Link: https://lkml.kernel.org/r/20251119095943.67125-1-xieyuanbin1@huawei.comSigned-off-by: Xie Yuanbin Acked-by: David Hildenbrand (Red Hat) Acked-by: Miaohe Lin Cc: Borislav Petkov Signed-off-by: Andrew Morton List of files: /linux/include/trace/events/memory-failure.h
