That's about ten times too large to be inlined.  Oh well.

Sometime could you please take a look at uninlining some of the porkier
functions in quotaops.h, and maybe convert them to lower case?



For the latter we can do

	#define DQUOT_ON_REMOUNT(sb) dquot_on_remount(sb)

etc, then remove those macros when everything has been converted and we've
given any out-of-tree filesytem developers time to update, etc.

Thanks.
