Yes. we can use page_is_ram() for finding (a)memory hole.
But I'd like to catch other removable PG_reserved pages like (d)Isorated
by MCA (e)used by perfmon and
some of (b) used by kernerl and (c) Set by drivers.
What I'm thinking of is to detect whether memory is hot-removable or not
before removing actually.
/dev/memstate really looks like a bad idea to me as well... I rather
have less than more /dev/*mem*
For showing page usage and its "location", I've thought of other
interface, sysfs, procfs...
But I have no idea.
Physical memory area has vast space and I want to use lseek() or
ioctl().( I don't like ioctl())
Do you have any recommendation ?
