vfs: fix reference leak in d_prune_aliases() In "d_prune_alias(): just lock the parent and call __dentry_kill()" the old dget + d_drop + dput has been replaced with lock_parent + __dentry_kill; unfortunately, dput() does more than just killing dentry - it also drops the reference to parent. New variant leaks that reference and needs dput(parent) after killing the child off. Signed-off-by: Yan, Zheng <zyan@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
