[XFS] fix 32-bit compat ioctls for GETXFLAGS, SETXFLAGS, GETVERSION
XFS_IOC_GETVERSION, XFS_IOC_GETXFLAGS and XFS_IOC_SETXFLAGS all take a "long" which changes size between 32 and 64 bit platforms. So, the ioctl cmds that come in from a 32-bit app aren't as expected, for example on GETXFLAGS, unknown cmd fd(3) cmd(80046601){t:'f';sz:4} due to the size mismatch. So, use instead the 32-bit version of the commands for compat ioctls, and other than that it doesn't take any more manipulation. Also, for both native and compat versions, just define them to the values as defined in fs.h SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:29849a Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com> Signed-off-by: Tim Shimmin <tes@sgi.com>
