only aiod does this and is also marked P_SYSTEM, the locations that reference p->p_vmspace usually do it within the context of the caller, the async access from the vm system is protected by the fact that it will skip over P_SYSTEM processes. Ok'd by: jhb

* Description of a process.

|
* This structure contains the information needed to manage a thread of
|
|
* control, known in UN*X as a process; it has references to substructures
|
|
* containing descriptions of things that the process uses, but may share
|
|
* with related processes. The process structure and the substructures
|
|
* are always addressable except for those marked "(CPU)" below,
|
|
* which might be addressable only on a processor on which the process
|
|
* is running.
|
|
*
|
|
* Below is a key of locks used to protect each member of struct proc. The
|
|
* lock is indicated by a reference to a specific character in parens in the
|
|
* associated comment.
|
|
* * - not yet protected
|
|
* a - only touched by curproc or parent during fork/wait
|
|
* b - created at fork, never changes
|
|
* (exception aiods switch vmspaces, but they are also
|
|
* marked 'P_SYSTEM' so hopefully it will be left alone)
|
|
* c - locked by proc mtx
|
|
* d - locked by allproc_lock lock
|
|
* e - locked by proctree_lock lock
|
|
* f - session mtx
|
|
* g - process group mtx
|
|
* h - callout_lock mtx
|
|
* i - by curproc or the master session mtx
|
|
* j - locked by sched_lock mtx
|
|
* k - either by curproc or a lock which prevents the lock from
|
|
* going away, such as (d,e)
|
|
* l - the attaching proc or attaching proc parent
|
|
* m - Giant
|
|
* n - not locked, lazy
|
|
*
|
|
* If the locking key specifies two identifiers (for example, p_pptr) then
|
|
* either lock is sufficient for read access, but both locks must be held
