This file is needed because Quota support on Linux has
been broken since Linus kernel 2.4.x. It will only get
better (and this file be removed) when all the distributions
ship a glibc with a working quota.h file. This is very
bad. JRA.
Original file came from Christoph Hellwig <hch@infradead.org>.
Massaged into one nasty include file (to stop us having to
add multiple files into Samba just for Linux braindamage)
by JRA.
