[PATCH v2 1/2] selftests/damon: suppress compiler warnings for huge_count_read_write

From: Yuanchu Xie
Date: Tue May 03 2022 - 20:04:32 EST


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.
