Alexey Dobriyan 22b5a48ac8 proc: fix dentry/inode overinstantiating under /proc/${pid}/net ... [ Upstream commit 7055197705709c59b8ab77e6a5c7d46d61edd96e ] When a process exits, /proc/${pid}, and /proc/${pid}/net dentries are flushed. However some leaf dentries like /proc/${pid}/net/arp_cache aren't. That's because respective PDEs have proc_misc_d_revalidate() hook which returns 1 and leaves dentries/inodes in the LRU. Force revalidation/lookup on everything under /proc/${pid}/net by inheriting proc_net_dentry_ops.
