In the Linux kernel, the following vulnerability has been resolved: nfs: Clean up /proc/net/rpc/nfs when nfs_fs_proc_net_init() fails. syzbot reported a warning below [1] following a fault injection in nfs_fs_proc_net_init(). [0] When nfs_fs_proc_net_init() fails, /proc/net/rpc/nfs is not removed. Later, rpc_proc_exit() tries to remove /proc/net/rpc, and the warning is logged as the directory is not empty. Let's handle the error of nfs_fs_proc_net_init() properly.
