The test case added in commit db7a347b26fe ("mm/damon/dbgfs: use '__GFP_NOWARN' for user-specified size buffer allocation") intentionally writes and reads with a large count to cause allocation failure and check for kernel warnings. We suppress the compiler warnings for these calls as they work as intended.
