From 3803d6721baff3d5dd6cd6b8c7294e54d124bc41 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 2 Feb 2020 17:53:55 -0500 Subject: NFS: Use kmemdup_nul() in nfs_readdir_make_qstr() The directory strings stored in the readdir cache may be used with printk(), so it is better to ensure they are nul-terminated.
