Not sure how much "maintenance" is required, the resize is successful if and only if the end result (the resized area) still has one or more unmapped pages at both ends. That's the check_area_conflicts() job. I still believe we can implement guarded address space areas with a ~15 lines patch and I think my proposal has some merits: no flags, no memory wasted to achieve that, paving the way for something similar to OpenBSD's malloc. If you want I could try to implement it this evening just to see if it makes sense. -- -------------------- Maurizio Lombardi _______________________________________________ HelenOS-devel mailing list [email protected] http://lists.modry.cz/cgi-bin/listinfo/helenos-devel
