Until now, our kernel has reimplemented a number of AK classes to
provide automatic internal locking:
- RefPtr
- NonnullRefPtr
- WeakPtr
- Weakable
This patch renames the Kernel classes so that they can coexist with
the original AK classes:
- RefPtr => LockRefPtr
- NonnullRefPtr => NonnullLockRefPtr
- WeakPtr => LockWeakPtr
- Weakable => LockWeakable
The goal here is to eventually get rid of the Lock* classes in favor of
using external locking.
Previously, we could only release *all* clean pages.
This patch makes it possible to release a specific amount of clean
pages. If the attempted number of pages to release is more than the
amount of clean pages, all clean pages will be released.
This commit moves the allocation of the resources required for
InodeVMObject from its constructors to the constructors of its child
classes.
We're making this change to give the child classes the chance to expose
the fallibility of the allocation.
