okay, just as update, we tracked this down to
the fact that even mainline 2.6.15/2.6.16-rc3
does not release ext3 filesystems properly
when the namespace is destroyed ... this can
be easily verified with a mainline kernel and
the following command sequence:
vnamespace --new -- mount /dev/hda1 /mnt
(assuming that /dev/hda1 contains an ext3 fs
and /mnt exists, this will claim hda1 but not
release it -- it works fine with ext2 though)
now investigating ...
best,
Herbert
