this patch is very interesting. BTW: Are you think this function name must be "relative" ? I think "relative" implies ordered set. but linux bitmap is abstraction of unordered set. if possible, i prefer another name. end up, bitmap_relative is map as pecial case, i think. > This is initially to be used by the MPOL_F_RELATIVE_NODES > facility being considered for mm/mempolicy.c. agreed with node_relative idea. I think this is very useful.
