Subject: ir: stream.c: do not truncate file at each packet flush
X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=08852d6e984f19911752f78c4de9cbc4bb82ba8d

ir: stream.c: do not truncate file at each packet flush

The whole stream file is truncated in bt_ctf_stream_destroy() anyway so
truncating at each packet flush is redundant.
