Subject: [PATCH 1/2] um/x86: Add system call table to header file
Date: Thu, 03 Jul 2025 14:38:54 +0200 [thread overview]
Message-ID: <20250703-uml-have_syscall_tracepoints-v1-1-23c1d3808578@linutronix.de> (raw)
In-Reply-To: <20250703-uml-have_syscall_tracepoints-v1-0-23c1d3808578@linutronix.de>
The generic system call tracing infrastructure requires access to the
system call table. The symbol is already visible to the linker but is
lacking a public declaration.
Add a public declaration.
