Subject: [PATCH] NFSv4: Ensure gcc 4.4.4 can compile initialiser for "invalid_stateid"
Date: Sat, 18 Nov 2017 13:50:11 -0500	[thread overview]
Message-ID: <20171118185011.4729-1-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <cce6f1be-0481-4ecc-85e2-a626cf381ce3@oracle.com>

gcc 4.4.4 is too old to have full C11 anonymous union support, so
the current initialiser fails to compile.
