Merge branch 'net-refcount_t'

Elena Reshetova says:

====================
v3 net generic subsystem refcount conversions

Changes in v3:
Rebased on top of the net-next tree.

Changes in v2:
No changes in patches apart from rebases, but now by
default refcount_t = atomic_t (*) and uses all atomic standard operations
unless CONFIG_REFCOUNT_FULL is enabled. This is a compromise for the
systems that are critical on performance (such as net) and cannot accept even
slight delay on the refcounter operations.

This series, for core network subsystem components, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
These patches contain only generic net pieces. Other changes will be sent separately.

The patches are fully independent and can be cherry-picked separately.
The big patches, such as conversions for sock structure, need a very detailed
look from maintainers: refcount managing is quite complex in them and while
it seems that they would benefit from the change, extra checking is needed.
The biggest corner issue is the fact that refcount_inc() does not increment
from zero.

If there are no objections to the patches, please merge them via respective trees.

* The respective change is currently merged into -next as
  "locking/refcount: Create unchecked atomic_t implementation".
