Subject: Ignore any snapshot directory with creation time > completion time.
X-Git-Tag: v0.1.1~2
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=df465017098a79eaa7b1c1c2f958f262b4dc521e;p=dss.git

Ignore any snapshot directory with creation time > completion time.

Without this fix, dss would abort du to an assertion in dss.c:

	dss.c:171: compute_next_snapshot_time: Assertion `x >= 0' failed.

Thanks to Sebastian Stark for pointing out this flaw.
