The reasons are: 1) there has not been a difference since i_mmap and i_mmap_shared for a few years, so there is no need to maintain separate trees for each 2) with the object based rmap, there IS a difference between normal and nonlinear VMAs, so those do need different lists > If I create a shared linear mapping, will it be kept in any of > these lists? Yes, a shared linear mapping will end up in the i_mmap tree. > Or maybe the i_mmap comment is misleading, and now i_mmap maps > linear vmas? You guessed it right. Maybe it's time to send in your first kernel patch, fixing the comment ? ;) Rik -- "Debugging is twice as hard as writing the code in the first place.
