Description
In the Linux kernel, the following vulnerability has been resolved:
spufs: fix a leak on spufs_new_file() failure
It's called from spufs_fill_dir(), and caller of that will do
spufs_rmdir() in case of failure. That does remove everything
we'd managed to create, but... the problem dentry is still
negative. IOW, it needs to be explicitly dropped.
