Subject: [PATCH v2 3/4] riscv: use TASK_TI_CPU instead of TASK_TI_CPU_NUM
Date: Fri, 25 Jul 2025 18:54:11 +0200 [thread overview]
Message-ID: <20250725165410.2896641-6-rkrcmar@ventanamicro.com> (raw)
In-Reply-To: <20250725165410.2896641-3-rkrcmar@ventanamicro.com>
The offsets of TASK_TI_CPU and TASK_TI_CPU_NUM are identical, and
TASK_TI_CPU is a better name for thread_info.cpu.
Reviewed-by: Alexandre Ghiti <alexghiti@rivosinc.com>
