Subject: [RFC PATCH v1 12/13] syscalls: add generic spawn template entries
Date: Thu, 28 May 2026 17:52:33 +0800 [thread overview]
Message-ID: <20260528095235.2491226-13-me@linux.beauty> (raw)
In-Reply-To: <20260528095235.2491226-1-me@linux.beauty>
Add spawn_template_create() and spawn_template_spawn() to the generic
syscall table and asm-generic UAPI numbering. This lets architectures
using the generic table pick up the spawn-template ABI instead of
leaving the mechanism x86-only.
Signed-off-by: Li Chen <me@linux.beauty>
