Subject: [PATCH 1/5] arm64: vdso: Use GFP_KERNEL for allocating compat vdso and signal pages
Date: Thu, 18 Mar 2021 17:07:34 +0000 [thread overview]
Message-ID: <20210318170738.7756-2-will@kernel.org> (raw)
In-Reply-To: <20210318170738.7756-1-will@kernel.org>
There's no need to allocate the compat vDSO and signal pages using
GFP_ATOMIC allocations, so use GFP_KERNEL instead.
