Hello Konstantin, Thanks for reacting on this issue.
> Please, evaluate the patch. If it does what you need - It doesn't change the manual page mincore.2. - For unmapped areas, it appears to be filling in values of -1 into the array. This is not what Linux, Solaris, NetBSD do: They return -1 from the system call and set errno to ENOMEM. See Linux: http://linux.about.com/library/cmd/blcmdl2_mincore.htm Solaris: http://docs.sun.com/app/docs/doc/816-5167/6mbb2jaib?a=view NetBSD: http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libc/sys/mincore.2?rev=1.19&content-type=text/plain - Filling in values of -1 into the array will confuse existing applications, because -1 is all bits set, i.e. the nonexistent pages will appear to be in-core, modified, referenced. - Filling in values of -1 into the array could be done more easily by changing the statements in sys/vm/vm_mmap.c lines 861 and 902. Thanks.
