[PATCH 3/3] xfs: rt stubs should return negative errnos when rt disabled

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

When realtime support is not compiled into the kernel, these functions
should return negative errnos, not positive errnos.  While we're at it,
fix a broken macro declaration.
