Subject: tdb2: restore file filling code.
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=2a585ebca2a23c536520d854749fc6a813e9b12a

tdb2: restore file filling code.

This snuck in fe55330a which added the stats attribute.  Without it,
TDB works but is vulnerable to segmenation faults or write errors when
disk is exhausted.
