Subject: [PATCH 4/9] gnttab: drop GNTMAP_can_fail
Date: Thu, 26 Aug 2021 12:13:00 +0200	[thread overview]
Message-ID: <761f3ea8-bfc9-4a8b-7878-2ff9e3047309@suse.com> (raw)
In-Reply-To: <eb7bbd51-1da3-9a7f-27c7-49dea1a41488@suse.com>

There's neither documentation of what this flag is supposed to mean, nor
any implementation. With this, don't even bother enclosing the #define-s
in a __XEN_INTERFACE_VERSION__ conditional, but drop them altogether.
