https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273956 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #12 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Ed Maste from comment #10) So what is the problem? 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.=
