[PATCH 3/5] uapi: merge the 32-bit mips struct flock into the generic one
From: Christoph Hellwig <hch@lst.de>
Date: 2022-01-31 06:50:06
Also in:
linux-arch, linux-mips, linux-s390, linuxppc-dev, lkml, sparclinux
Subsystem:
generic include/asm header files, mips, the rest · Maintainers:
Arnd Bergmann, Thomas Bogendoerfer, Linus Torvalds
Add a new __ARCH_FLOCK_EXTRA_SYSID macro following the style of __ARCH_FLOCK_PAD to avoid having a separate definition just for one architecture.
