-Userspace VAs
---------------------
-To maintain compatibility with software that relies on the VA space with a
-maximum of 48 bits the kernel will, by default, return virtual addresses to
-userspace from a 48-bit range (sv48). This default behavior is achieved by
-passing 0 into the hint address parameter of mmap. On CPUs with an address space
-smaller than sv48, the CPU maximum supported address space will be the default.
-
-Software can "opt-in" to receiving VAs from another VA space by providing
-a hint address to mmap. When a hint address is passed to mmap, the returned
-address will never use more bits than the hint address. For example, if a hint
-address of `1 << 40` is passed to mmap, a valid returned address will never use
-bits 41 through 63. If no mappable addresses are available in that range, mmap
-will return `MAP_FAILED`.

+Netdev remains skeptical about promises of all "auto-cleanup" APIs,
+including even ``devm_`` helpers, historically. They are not the preferred
+style of implementation, merely an acceptable one.
+
+Use of ``guard()`` is discouraged within any function longer than 20 lines,
+``scoped_guard()`` is considered more readable. Using normal lock/unlock is
+still (weakly) preferred.
+
+Low level cleanup constructs (such as ``__free()``) can be used when building
+APIs and helpers, especially scoped iterators. However, direct use of
+``__free()`` within networking core and drivers is discouraged.
+Similar guidance applies to declaring variables mid-function.
