Subject: [dm-devel] [PATCH AUTOSEL 5.9 04/23] dm integrity: don't use drivers that have CRYPTO_ALG_ALLOCATES_MEMORY
Date: Sat, 12 Dec 2020 11:07:45 -0500 [thread overview]
Message-ID: <20201212160804.2334982-4-sashal@kernel.org> (raw)
In-Reply-To: <20201212160804.2334982-1-sashal@kernel.org>
From: Mikulas Patocka <mpatocka@redhat.com>
[ Upstream commit a7a10bce8a04f48238a8306ec97d430b77917015 ]
Don't use crypto drivers that have the flag CRYPTO_ALG_ALLOCATES_MEMORY
set. These drivers allocate memory and thus they are not suitable for
block I/O processing.
