VMO representing a physical range of memory
Public Methods
Lock<CriticalMutex> * lock ()Define the lock retrieval functions differently depending on whether we should be returning a
local lock instance, or the common one in the hierarchy_state_ptr. Due to the TA_RET_CAP
statements we cannot perform |if constexpr| or equivalent indirection in the function body, and
must have two completely different function definitions.
In the absence of a local lock it is assumed, and enforced in vm_object_lock.h, that there is a
shared lock in the hierarchy state. If there is both a local and a shared lock then the local
lock is to be used for the improved lock tracking.
