Thank you for the responses! I recently came across the `compact_unevictable_allowed` sysctl option and it seems like it could be a good fit for our use case. Setting it to 0 would prevent the kernel from compacting/migrating locked pages, which should eliminate the minor faults we're seeing during compaction. Could we possibly set `compact_unevictable_allowed=0` by default when CONFIG_EVL is enabled? https://www.infradead.org/~mchehab/kernel_docs/admin-guide/sysctl/vm.html#compact-unevictable-allowed
