docs: sysctl: Add documentation for /proc/sys/xen/

2026-04-09T14:44:31+00:00

Add documentation for the Xen hypervisor sysctl controls in /proc/sys/xen/balloon/. Documents the hotplug_unpopulated tunable (available when CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is enabled) which controls whether unpopulated memory regions are automatically hotplugged when the Xen balloon driver needs to reclaim memory. The documentation is based on source code analysis of drivers/xen/balloon.c.

docs: admin-guide: move sysctl directory to it

2019-07-15T14:03:01+00:00

The stuff under sysctl describes /sys interface from userspace point of view. So, add it to the admin-guide and remove the :orphan: from its index file. Signed-off-by: Mauro Carvalho Chehab
