Subject: [PATCH 00/17] net subsystem refcount conversions
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.
Since we convert all kernel subsystems in the same fashion, resulting
in about 300 patches, we have to group them for sending at least in some
fashion to be manageable. Please excuse the long cc list.
If there are no objections to the patches, please merge them via respective trees.
