Here is a race when someone umounted something and this operation
isn't propagated into our namespace.
CRIU | Another process
-----------------------------------------------------------------
pivot_root(".", put_root) |
mount(put_root, MS_REC|MS_PRIVATE) |
| umount /xxx/yyy
| umount /xxx -> EBUSY
umount(put_root)
We do this to not affect mounts in put_root, but we can mask
these mounts as slave and this will work for us and for external
users.
