Allocations for zero length files

["Karl O. Pinc" <kop@xxxxxxxx>]

Hi,

If I make a zero length file in xfs is any disk allocated for the
data portion?  I'm thinking of storing lots (units of 10**6) of
small keys as empty files with names that are the keys.

I suppose some keys could be larger, is there a limit on filename
length?

(Thanks for not making me go to the trouble of coming up with
some free partition space to try this out.  I'm afriad
of loopback mount lockups, although maybe that was
all related to Linux 2.4.)
