From 306f7cc1e9061313c46d19e9bdffc819880794c1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 5 Apr 2022 15:12:56 +0800 Subject: uapi: always define F_GETLK64/F_SETLK64/F_SETLKW64 in fcntl.h The F_GETLK64/F_SETLK64/F_SETLKW64 fcntl opcodes are only implemented for the 32-bit syscall APIs, but are also needed for compat handling on 64-bit kernels. Consolidate them in unistd.h instead of definining the internal compat definitions in compat.h, which is rather error prone (e.g. parisc gets the values wrong currently). Note that before this change they were never visible to userspace due to the fact that CONFIG_64BIT is only set for kernel builds.
