Descriptions

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

smb3: fix temporary data corruption in collapse range

collapse range doesn't discard the affected cached region
so can risk temporarily corrupting the file data. This
fixes xfstest generic/031

I also decided to merge a minor cleanup to this into the same patch
(avoiding rereading inode size repeatedly unnecessarily) to make it
clearer.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: smb3: corrige la corrupción temporal de datos en el rango de contracción el rango de contracción no descarta la región en caché afectada, por lo que puede correr el riesgo de corromper temporalmente los datos del archivo. Esto corrige xfstest generic/031. También decidí fusionar una limpieza menor en el mismo parche (evitando volver a leer el tamaño del inodo repetidamente innecesariamente) para que quede más claro.
