To: "gregkh@xxxxxxxxxxxxxxxxxxx" <gregkh@xxxxxxxxxxxxxxxxxxx>
Cc: "stable@xxxxxxxxxxxxxxx" <stable@xxxxxxxxxxxxxxx>

From: Seth Forshee <seth.forshee@xxxxxxxxxxxxx>
[ Upstream commit 5f65e5ca286126a60f62c8421b77c2018a482b8a ]
Using INVALID_[UG]ID for the LSM file creation context doesn't
make sense, so return an error if the inode passed to
set_create_file_as() has an invalid id.
