I should note that, for 8.2, this will enable a rewrite of
open_self_maps_1 so that it
does not require page-by-page checking of page_get_flags.
My idea is that open_self_maps_1 would use walk_memory_regions to see
all guest memory
regions. The per-region callback would cross-check with the host-
region interval tree to
find the dev+inode+path.
Cc Ilya and Helge, since there are two outstanding changes to
open_self_maps.
I think the rewrite is good.
My patches regarding the map aren't important, I can adjust them
afterwards and resend (if necessary).
