Patch series "New selftest for mm", v2. This is a simple test case that reproduces an mm problem[1], where a page fault races with madvise(), and it is not trivial to reproduce and debug. This test-case aims to avoid such race problems from happening again, impacting workloads that leverages external allocators, such as tcmalloc, jemalloc, etc. [1] https://lore.kernel.org/all/20231001005659.2185316-1-riel@surriel.com/#r This patch (of 2): get_free_hugepages() is helpful for other hugepage tests. Export it to the common file (vm_util.c) to be reused.
