[PATCH 00/17] Treewide: enforce static storage for object initializers

[Yury Norov <ynorov@nvidia.com>]

On top of [1].

Declaration macros that statically initialize embedded locks require static
storage when lockdep is enabled. Automatic objects must use runtime
initialization so lockdep receives a persistent class key.

For automatic local objects, lockdep cannot use the lock address as a persistent
class key and reports "INFO: trying to register non-static key" before disabling
itself.

Series [1] introduces an ASSERT_STATIC_STORAGE() macro to enforce static
duration of an object, and applies it for DEFINE_IDA() and DEFINE_MTREE().

This series applies the same mechanism for the other structures of that
sort found by Codex.

[1] also describes the preferred route(s) for the material. According to
Andrew's (and mine) preferences, sending everything together in the hope
that the relevant maintainers would ack the corresponding patches or
simply take them in their trees.
