Subject: [PATCH v2 01/29] ia64: add __NR_umount2 definition
Date:   Fri, 18 Jan 2019 17:18:07 +0100
Message-Id: <20190118161835.2259170-2-arnd@arndb.de>
In-Reply-To: <20190118161835.2259170-1-arnd@arndb.de>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Precedence: bulk

Other architectures commonly use __NR_umount2 for sys_umount,
only ia64 and alpha use __NR_umount here. In order to synchronize
the generated tables, use umount2 like everyone else, and add back
the old name from asm/unistd.h for compatibility.

The __IGNORE_* lines are now all obsolete and can be removed as
a side-effect.
