Subject: [PATCH 00/29] drivers, mics refcount conversions
This series, for various different drivers, 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.
The below 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.
*with the exception of the media/vb2-related patches that depend on
vb2_vmarea_handler.refcount conversions.
Not run-time tested beyond booting and using kernel with refcount conversions
for my daily work.
If there are no objections to these patches,
I think they can go via Greg's drivers tree, as he suggested before.
