The 9p fs does not use IDR or IDA functionalities. So there is no point in
including <linux/idr.h>.
Remove it.

Right, it's used by net/9p/client.c only. Probably some more files in net/9p
could therefore be deflated as well. Anyway:

Hi,
i was unsure if net/9p and fs/9p should be patched at the same time or not.

I'll send another patch for net/9p.

I'd go out a limb and write it as 'Remove unneeded idr.h #include',
but this nitpick aside this looks good to me;
I'll pick it for next cycle.
