Description

Relates to LU-2298

It seems that changelog is not logging file truncates. I've not tested 2.4.1 but when I do I'll update this.

[root@coolermaster lustre]# dd if=/dev/zero of=truncate bs=1M count=10

Possibly the wrong flag 'SATTR' is being sent here, as when I reduce the mask down to just TRUNC flag nothing comes through at all.
