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.

Ivan Shapovalov (2):
configure.in: check for fallocate() and related headers.
Add aal_device_discard() function and implement it for file-based
device.
