Subject: [REVIEW PATCH v5 2/3] arch: wire-up close_range()
Date: Fri, 25 Oct 2019 14:28:50 +0200	[thread overview]
Message-ID: <20191025122851.30182-3-christian.brauner@ubuntu.com> (raw)
In-Reply-To: <20191025122851.30182-1-christian.brauner@ubuntu.com>

This wires up the close_range() syscall into all arches at once.

introduced
- Arnd Bergmann <arnd@arndb.de>:
  - split into two patches:
    1. add close_range()
    2. add syscall to all arches at once
  - bump __NR_compat_syscalls in arch/arm64/include/asm/unistd.h
