The leading / is originating in jrecord_write_path in vfs_journal.c,
I added some debug which revealed that the chain of namecache structures
ends with an extra one with nc_nlen set to 0. I have no idea if this extra
record is vital for some purpose so I've added the attached patch to make
jrecord_write_path ignore it rather than try and track down where it is
coming from and remove it (I'd hate to destabilise the namecache stuff -
even in a vkernel).
Unfortunately it's not enough to make the mirror work - something
seems to be astray in jscan - I'll look into that next.
PS: The vkernel is *wonderful* :)
