See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-mips@vger.kernel.org The fcntl F_GETLK64/F_SETLK64/F_SETLKW64 are only implemented for the 32-bit syscall APIs, but we also need them for compat handling on 64-bit builds. Redefining them is error prone (as shown by the example that parisc gets it wrong currently), so we should use the same defines for both case. In theory we could try to hide them from userspace, but given that only MIPS actually gets that right, while the asm-generic version used by most architectures relies on a Kconfig symbol that can't be relied on to be set properly by userspace is a clear indicator to not bother.
