Difference between vnode/swap is due to how kernel handles partial pages vs. ld-elf.so.1. Kernel allocates separate anon object to map such page, and copies data into it from the segment, see imgact_elf.c:map_partial(). ld-elf.so.1 just mmaps for CoW. --=20 You are receiving this mail because: You are the assignee for the bug.=
