CVE-2021-47167

Description

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix an Oopsable condition in __nfs_pageio_add_request() Ensure that nfs_pageio_error_cleanup() resets the mirror array contents, so that the structure reflects the fact that it is now empty. Also change the test in nfs_pageio_do_add_request() to be more robust by checking whether or not the list is empty rather than relying on the value of pg_count.
