I'm sorry, but I have absolutely no idea what this means.
>From the rationale it sounds like s390 stashes some kind of label or
bootable area at the end of a minidisk, which is visible to the Linux
program accessing the device file, and that mke2fs is supposed to
somehow recognize the RECOMP area (how?), figure out how big is it
(how?) and when mke2fs is not given a filesystem size, to pick by
default a new filesystem size which hdoesn't overwrite the RECOMP
area.
Did I guess this correctly? If so, you're going to have to tell me
how to do this, or better yet, supply code (patches) which does this.
Thanks, regards,
