From: kovalev@altlinux.org To: devel@lists.altlinux.org Cc: Vasiliy Kovalev <kovalev@altlinux.org> Subject: [devel] [PATCH 1/1] Revert "scsi: aacraid: Reply queue mapping to CPUs based on IRQ affinity" Date: Tue, 5 Dec 2023 20:23:13 +0300 Message-ID: <20231205172313.107219-2-kovalev@altlinux.org> (raw) In-Reply-To: <20231205172313.107219-1-kovalev@altlinux.org> From: Vasiliy Kovalev <kovalev@altlinux.org> This reverts commit 7d1ac3c2eb70558d2b4c1ec9d966000d4cc6b353. This is a temporary solution that reverses the changes to the aacraid driver that led to periodic hungs of the adaptec raid controller. The decision is valid for December 4, 2023.
