linuxkpi compiler.h: avoid gcc -Wunused-value in dummy expressionsIt looks like the __acquire and __release macros are for the consumptionof static analysis tools and have no semantic effect. Transform thedefinitions from constant expressions to empty statements in order toavoid -Wunused-value from gcc.Likewise avoid future warnings for __chk_{user,io}_ptr, but with a castto void, because it looks like some linux kernel code may use those inexpression contexts.Reviewed by: hselasky, markjApproved by: markj (mentor)Sponsored by: Dell EMC IsilonDifferential Revision: https://reviews.freebsd.org/D11695 List of files: /freebsd-13.1/sys/compat/linuxkpi/common/include/linux/compiler.h

21b73749 - Introduce __read_mostly and __exclusive_cache_line macros.

Fri, 27 Jan 2017 14:53:09 +0000

Introduce __read_mostly and __exclusive_cache_line macros.The intended use is to annotate frequently used globals which either rarelychange (and thus can be grouped in the same cacheline) or are an atomic counter(which means it may benefit from being the only variable in the cacheline).Linker script support is provided only for amd64. Architectures without it riskhaving other variables put in, i.e. as if they were not annotated. This isharmless from correctness point of view.Reviewed by: bde (previous version)MFC after: 1 month List of files: /freebsd-13.1/sys/compat/linuxkpi/common/include/linux/compiler.h
