[PATCH] epoll: fix delayed initialization bug
Al found a potential problem in epoll_create(), where the
file->private_data member was set after fd_install(). This is obviously
wrong since another thread might do a close() on that fd# before we set the
file->private_data member. This goes over 2.6.13 and passes a few basic
tests I've done here.
(akpm: snuck in a kzalloc() cleanup too)
