Subject: [PATCH 102/109] kexec: move sys_kexec_load() prototype to syscalls.h
Date: Thu, 29 Mar 2018 13:24:19 +0200 [thread overview]
Message-ID: <20180329112426.23043-103-linux@dominikbrodowski.net> (raw)
In-Reply-To: <20180329112426.23043-1-linux@dominikbrodowski.net>
As the syscall function should only be called from the system call table
but not from elsewhere in the kernel, move the prototype for
sys_kexec_load() to include/syscall.h.
