This adds new rounding macros to round to closest integer along with enabling KUnit tests for all math.h macros. It also updates kernel-doc to render math.h related documentation and lastly updates the imagination jpeg encoder to use the newly introduced rounding macros to find nearest value. Also to note that math.h is orphaned and so these changes need to be pulled by subsystem using it as a first as discussed in below threads: Link: https://lore.kernel.org/all/1db64af7-3688-4bcc-a671-9440d8f02d1a@xxxxxxxxx/ https://lore.kernel.org/all/ZmHDWeuezCEgj20m@xxxxxxxxxxxxxxxxxx/ Daniel Latypov (1): lib: Add basic KUnit test for lib/math Devarsh Thakkar (5): math.h: Add macros for rounding to closest value math.h: Use kernel-doc syntax for divison macros Documentation: core-api: Add math.h macros and functions lib: math_kunit: Add tests for new macros related to rounding to nearest value media: imagination: Round to closest multiple for cropping region Documentation/core-api/kernel-api.rst | 6 + .../platform/imagination/e5010-jpeg-enc.c | 8 +- include/linux/math.h | 86 ++++- lib/math/Kconfig | 14 + lib/math/Makefile | 1 + lib/math/math_kunit.c | 329 ++++++++++++++++++ 6 files changed, 434 insertions(+), 10 deletions(-) create mode 100644 lib/math/math_kunit.c -- 2.39.1
