Subject: [PATCH 3/5] uapi: merge the 32-bit mips struct flock into the generic one
Date: Mon, 12 Apr 2021 10:55:43 +0200 [thread overview]
Message-ID: <20210412085545.2595431-4-hch@lst.de> (raw)
In-Reply-To: <20210412085545.2595431-1-hch@lst.de>
Add a new __ARCH_FLOCK_EXTRA_SYSID macro following the style of
__ARCH_FLOCK_PAD to avoid having a separate definition just for one
architecture.
Signed-off-by: Christoph Hellwig <hch@lst.de>
