[PATCH 0/3] selftests/mm: add memory failure selftests

[Miaohe Lin <linmiaohe@huawei.com>]

Introduce selftests to validate the functionality of memory failure. 
These tests help ensure that memory failure handling for anonymous
pages, pagecaches pages works correctly, including proper SIGBUS
delivery to user processes, page isolation, and recovery paths.

Currently madvise syscall is used to inject memory failures. And only
anonymous pages and pagecaches are tested. More test scenarios, e.g.
hugetlb, shmem, thp, will be added. Also more memory failure injecting
methods will be supported, e.g. APEI Error INJection, if required.

Thanks!
