Well the problem I was working on was when a mount like
the following is done:
mount server://export /mnt
the umount /mnt will fail because the device name was written to
/proc/mounts has the // stripped:
server:/export /mnt nfs4 rw,relatime,vers=4...
but the device name in the mtab did not:
rhelhat://home /mnt/home nfs rw,vers=4,...
So what my patch does is "normalizes" the device name early
on in main, so the correct name used used through the mount
and when its written the mtab. Plus, for better or worses,
since the new device name will always be shorter, I just
reuse/rewrite the memory allocated for the argv vector..
Meaning there is no allocation...
steved.
