Qu Wenruo a2203246ae btrfs-progs: Introduce kernel sizes to cleanup large intermediate number
Large numbers like (1024 * 1024 * 1024) may cost reader/reviewer to
waste one second to convert to 1G.

Introduce kernel include/linux/sizes.h to replace any intermediate
number larger than 4096 (not including 4096) to SZ_*.
