move d_rcu from overlapping d_child to overlapping d_alias
commit 946e51f2bf37f1656916eb75bd0742ba33983c28 upstream.
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
[bwh: Backported to 3.2:
- Apply name changes in all the different places we use d_alias and d_child
- Move the WARN_ON() in __d_free() to d_free() as we don't have dentry_free()]
Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
[lizf: Backported to 3.4:
- adjust context
- need one more name change in debugfs]
