Subject: [PATCH AUTOSEL 4.14 15/16] ufs: fix braino in ufs_get_inode_gid() for solaris UFS flavour
Date: Thu, 16 May 2019 07:41:06 -0400	[thread overview]
Message-ID: <20190516114107.8963-15-sashal@kernel.org> (raw)
In-Reply-To: <20190516114107.8963-1-sashal@kernel.org>

From: Al Viro <viro@zeniv.linux.org.uk>

[ Upstream commit 4e9036042fedaffcd868d7f7aa948756c48c637d ]

To choose whether to pick the GID from the old (16bit) or new (32bit)
field, we should check if the old gid field is set to 0xffff.  Mainline
checks the old *UID* field instead - cut'n'paste from the corresponding
code in ufs_get_inode_uid().
