[PATCH] d_instantiate_unique / NFS inode leakage

 *

 * Fill in inode information in the entry. On success, it returns NULL.

 * If an unhashed alias of "entry" already exists, then we return the

 * aliased dentry instead.

 * aliased dentry instead and drop one reference to inode.

 *

 * Note that in order to avoid conflicts with rename() etc, the caller

 * had better be holding the parent directory semaphore.

 *

 * This also assumes that the inode count has been incremented

 * (or otherwise set) by the caller to indicate that it is now

 * in use by the dcache.
