[dpdk-dev] [PATCH v4 1/5] vhost: eventfd_link: moving ioctl to a function

[Xie, Huawei]

Two opens here, the trivial one is i think it is not good practice to
explicitly inline non performance critical functions in c file, even if
it will be done by compiler anyway.
The critical one i have concern is whether it will introduce
inconsistency if we call fd_install on a fd that is just closed by
sys_close, because that fd will be set to next-to-be-allocated fd. I
prefer to keep the original logic in patch 4/5 if we are not clear.

As we actually don't need to use the eventfd that is allocated in user
space at all, future patch would be: directly allocate a new fd in the
kernel and call fd_install on it.
