These instances were detected by searching for files that include
Kernel/Debug.h, but don't match the regex:
\\bdbgln_if\(|_DEBUG\\b
This regex is pessimistic, so there might be more files that don't check
for any real *_DEBUG macro. There seem to be no corner cases anyway.
In theory, one might use LibCPP to detect things like this
automatically, but let's do this one step after another.
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.
This enforces us to remove duplicated code across the SysFS code. This
results in great simplification of how the SysFS works now, because we
enforce one way to treat SysFSDirectory objects.
