Subject: [PATCH RFC 2/6] mm, slab: Remove compiler check in __kmalloc_index
Date: Mon, 29 Nov 2021 09:57:59 -0700 [thread overview]
Message-ID: <20211129165803.470795-3-nathan@kernel.org> (raw)
In-Reply-To: <20211129165803.470795-1-nathan@kernel.org>
The minimum supported version of LLVM has been raised to 11.0.0, meaning
this check is always true, so it can be dropped.
