Re: [RFC] [PATCH 0/2] libaal: add device "discard" operation.

[Edward Shishkin <edward.shishkin@gmail.com>]

Great, thank you!

To our shame, reiser4 neither preallocates, nor punches holes.
TBH, too lazy ;) I prefer to concentrate on features, which are
either unique, or perform better in reiser4 (like discard)...

Thanks,
Edward.
