Re: possible bug in "--pad" option for mkfs.jffs2?

["Ryan B. Lynch" <rlynch@bway.net>]

I did a little more testing with this, and the "--pad" option doesn't
work AT ALL on my installation.  Something is definitely wrong, here.

I compiled JFFS2 from source, using a CVS snapshot from 2005/08/14, with
the "jffs2-summary-20050811-v2.patch" applied.

Can anyone confirm this?
