23 This file is needed because Quota support on Linux has
24 been broken since Linus kernel 2.4.x. It will only get
25 better (and this file be removed) when all the distributions
26 ship a glibc with a working quota.h file. This is very
27 bad. JRA.

29 Original file came from Christoph Hellwig <[email protected]>.
30 Massaged into one nasty include file (to stop us having to
31 add multiple files into Samba just for Linux braindamage)
32 by JRA.
