Hi folks, this the 3rd iteration of this patchset.

tl; dr: we are adding here error messages in case of failures when
reserve_mem parameter is used, and also a debugfs file to show
successful reservations, with name and size as passed in the cmdline.

More details and history, please take a look at:
