Subject: Re: [PATCH 02/10] lib: genalloc: Generic allocator improvements

I am curious about one thing

Why do we need this allocator. Why not use allocate_resource and friends.
The kernel generic resource handler already handles object alignment and
subranges. It just seems to be a surplus allocator that could perhaps be
mostly removed by using the kernel resource allocator we already have ?
