Hi!!
I'm studyng ext4 code, and i got a doubt on a situation:
Supposing a 4K page size, and a fs with 8K.. when we are filling page info,:
{ 4K page }{ 4K page }{ 4K page }{ 4K page }
[ group 0 bitmap ] [ group 0 buddy ]
Clearly bitmap and buddy info don't fits on a single page, but e4b
structure saves only one page address.
How mb allocator menages this situation??
Thanks!!!
