Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ceph: fix deadlock or deadcode of misusing dget()

The lock order is incorrect between denty and its parent, we should
always make sure that the parent get the lock first.

But since this deadcode is never used and the parent dir will always
be set from the callers, let's just remove it.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ceph: corrige el punto muerto o el código muerto por uso incorrecto de dget() El orden de bloqueo es incorrecto entre denty y su padre, siempre debemos asegurarnos de que el padre obtenga el bloqueo primero. Pero dado que este código muerto nunca se usa y el directorio principal siempre será configurado por quienes llaman, simplemente eliminémoslo.
