Subject: [PATCH 04/11] UAPI: bcache: Fix use of embedded flexible array
Date: Wed, 05 Sep 2018 16:55:03 +0100	[thread overview]
Message-ID: <153616290368.23468.7806230605345568524.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <153616286704.23468.584491117180383924.stgit@warthog.procyon.org.uk>

The bkey struct defined by bcache is embedded in the jset struct.  However,
this is illegal in C++ as there's a "flexible array" at the end of the
struct.  Change this to be a 0-length struct instead.
