Sri Jayaramappa bd67d5c15c Test compaction of mlocked memory ... Commit commit 5bbe3547aa ("mm: allow compaction of unevictable pages") introduced a sysctl that allows userspace to enable scanning of locked pages for compaction. This patch introduces a new test which fragments main memory and attempts to allocate a number of huge pages to exercise this compaction logic. Tested on machines with up to 32 GB RAM. With the patch a much larger number of huge pages can be allocated than on the kernel without the patch. Example output: On a machine with 16 GB RAM: sudo make run_tests vm ... ----------------------- running compaction_test ----------------------- No of huge pages allocated = 3834 [PASS] ...
