From 166126c1e54d927c2e8efa2702d420e0ce301fd9 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 1 Jul 2018 13:57:13 -0700 Subject: kernfs: Replace strncpy with memcpy gcc 8.1.0 complains: fs/kernfs/symlink.c:91:3: warning: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length fs/kernfs/symlink.c: In function 'kernfs_iop_get_link': fs/kernfs/symlink.c:88:14: note: length computed here Using strncpy() is indeed less than perfect since the length of data to be copied has already been determined with strlen(). Replace strncpy() with memcpy() to address the warning and optimize the code a little.
