Document mach_port_set_ktype
commit fdfca0e86009c5a7b188fa39e939de800a73391d
Author: Michael Kelly <[email protected]>
Date: Sun Aug 31 23:21:54 2025 +0200
Add mach_port_set_ktype RPC to set ktype of a user port
For now, we only allow a newly-introduced MACH_PORT_KTYPE_USER_DEVICE type
that makes ipc_kmsg_copyin_body use page lists, which keep them in a busy
state that prevents them from being paged out.
