[dpdk-dev] [PATCH v2] eal: clean up unused files on initialization

> When creating process data structures, EAL will create many files
> in EAL runtime directory. Because we allow multiple secondary
> processes to run, each secondary process gets their own unique
> file. With many secondary processes running and exiting on the
> system, runtime directory will, over time, create enormous amounts
> of sockets, fbarray files and other stuff that just sits there
> unused because the process that allocated it has died a long time
> ago. This may lead to exhaustion of disk (or RAM) space in the
> runtime directory.
> 
> Fix this by removing every unlocked file at initialization that
> matches either socket or fbarray naming convention. We cannot be
> sure of any other files, so we'll leave them alone. Also, remove
> similar code from mp socket code.
> 
> We do it at the end of init, rather than at the beginning, because
> secondary process will use primary process' data structures even
> if the primary itself has died, and we don't want to remove those
> before we lock them.

I feel it is too big and too late for 18.11.
Can we move it to 19.02?
