Subject: [PATCH v3] selftests/damon: suppress compiler warnings for huge_count_read_write
Date: Wed,  4 May 2022 18:29:08 +0000	[thread overview]
Message-ID: <20220504182908.1322874-1-yuanchu@google.com> (raw)
In-Reply-To: <20220504001153.119485-1-sj@kernel.org>

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.
