From: Joerg Roedel <jroe...@suse.de>
Hi,
a previous discussion pointed out that using atomic64_t for that
purpose is a bit of overkill. This patch-set replaces it with unsigned
long and introduces some helpers first to make the change more easy.
Qian, can you please test these patches in your environment? You can
trigger any race-condition there pretty reliably :)
Other than that, please review and test.
Regards,
Joerg
