Same here, waiter should not be woken up until the link memory is actually freed.
OK, I will correct this as well.
And similarly I want to move smc_ibdev_cnt_dec() and put_device() to
__smcr_link_clear() as well to ensure that put link related resources
only when link is actually cleared. What do you think?
Thanks,
