This commit introduces alloc_contig_freed_pages() function
The "freed" seems redundant to me. Wouldn't "alloc_contig_pages" be a
better name?
The “freed” is there because the function operates on pages that are in
buddy system, ie. it is given a range of PFNs that are to be removed
from buddy system.
There's also a alloc_contig_range() function (added by next patch)
which frees pages in given range and then calls
alloc_contig_free_pages() to allocate them.
IMO, if there was an alloc_contig_pages() function, it would have to
be one level up (ie. it would figure out where to allocate memory and
then call alloc_contig_range()). (That's really what CMA is doing).
Still, as I think of it now, maybe alloc_contig_free_range() would be
better?
