[Ocfs2-devel] [PATCH] ocfs2: fix the wrong directory passed to ocfs2_lookup_ino_from_name() when link file

[Aron Szabo <aron@ubit.hu>]

Hi Andew!

Hard linking works again, when paths are relative with at least one 
subdirectory. This is how the problem was reproducable:

# mkdir a
# mkdir b
# touch a/test
# ln a/test b/test
ln: failed to create hard link `b/test' => `a/test': No such file or 
directory

However when creating links in the same dir, it worked well.

Now the link gets created.

Thanks for the quick fix Xue!

Yours,
Aron
