Descriptions

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

cifs: fix warning when destroy 'cifs_io_request_pool'

There's a issue as follows:
WARNING: CPU: 1 PID: 27826 at mm/slub.c:4698 free_large_kmalloc+0xac/0xe0
RIP: 0010:free_large_kmalloc+0xac/0xe0
Call Trace:

Obviously, 'cifs_io_request_pool' is not created by mempool_create().
So just use mempool_exit() to revert 'cifs_io_request_pool'.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cifs: se corrige la advertencia al destruir 'cifs_io_request_pool' Hay un problema como el siguiente: ADVERTENCIA: CPU: 1 PID: 27826 en mm/slub.c:4698 free_large_kmalloc+0xac/0xe0 RIP: 0010:free_large_kmalloc+0xac/0xe0 Rastreo de llamadas: ? Obviamente, 'cifs_io_request_pool' no es creado por mempool_create(). Entonces simplemente use mempool_exit() para revertir 'cifs_io_request_pool'.
