Subject: [PATCH 1/3] s390x: fix condition to choose correct function
Date: Mon, 29 Feb 2016 18:04:12 -0600	[thread overview]
Message-ID: <1456790652-92638-1-git-send-email-smfrench@gmail.com> (raw)
In-Reply-To: <smfrench-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Yadan Fan <ydfan-IBi9RG/b67k@public.gmane.org>

This issue is involved from commit 02323db17e3a7 ("cifs: fix
cifs_uniqueid_to_ino_t not to ever return 0"), when BITS_PER_LONG
is 64 on s390x, the corresponding cifs_uniqueid_to_ino_t()
function will cast 64-bit fileid to 32-bit by using (ino_t)fileid,
because ino_t (typdefed __kernel_ino_t) is int type.
