[PATCH v2 0/2] Lock and Pointer guards

From: Peter Zijlstra
Date: Fri May 26 2023 - 17:01:17 EST

By popular demand, a new and improved version :-)

New since -v1 ( https://lkml.kernel.org/r/20230526150549.250372621@xxxxxxxxxxxxx )

- much improved interface for lock guards: guard() and scoped () { }
as suggested by Linus.
- moved the ';' for the 'last' additional guard members into the definition
as suggested by Kees.
- put __cleanup in the right place with the suggested comment
as suggested by Kees and Miguel
- renamed the definition macros DEFINE_LOCK_GUARD_[012] to indicate
the number of arguments the lock function takes
- added comments to guards.h
- renamed pretty much all guard types

Again compile and boot tested x86_64-defconfig
