Subject[PATCH] Attempt to hard link across filesystems results in un-unmountable filesystem
Hi Linus,

In 2.4-test11 attempting to hard link a file across filesystems (the
link does fail correctly) results in one of the filesystems (the one
the hard link was to be created on) to be in a state such that it
can't be unmounted.

The attached patch fixes this problem.

Chris.
