Are you ok with the name MEMSCRUB? I know previously you have objected to this
name, since it might get confused with UBI scrubbing
(http://lists.infradead.org/pipermail/linux-mtd/2010-September/032031.html). In
fact, the conclusion of that thread was to add an extended erase IOCTL, with a
'flags' parameter to capture options such as erase bad blocks. Would this be
the preferred method (it didn't seem to go anywhere last time), or is 'MEMSCRUB'
with the existing erase_info_user64 structure acceptable?
Cheers,
Angus
