Hi, Both bootmem and memblock have pretty good documentation coverage. With some fixups and additions we get a nice overall description. The last commit in the series that creates the boot-time-mm.rst depends on the 'nodoc' sphix directive patch [1] I've sent earlier While working on the docs, I've noticed that both bootmem and nobootmem implement some one-line wrappers for the core allocation methods as a global functions rather than 'static inline'. I wonder whether I miss something important here is it just a historic thing?
