Subject: [PATCH v4 14/18] riscv32: Specify the arch_minimum_kernel as 5.4
Date: Wed, 12 Aug 2020 07:41:44 -0700 [thread overview]
Message-ID: <d528a4138ff8db82da2284b7d2249c911b819992.1597243100.git.alistair.francis@wdc.com> (raw)
In-Reply-To: <cover.1597243100.git.alistair.francis@wdc.com>
Specify the minimum kernel version for RISC-V 32-bit as the 5.4 kernel.
We require this commit: "waitid: Add support for waiting for the current
process group" for the kernel as it adds support for the P_PGID id for
the waitid syscall. Without this patch we can't replace the wait4
syscall on 64-bit time_t only systems.
