[PATCH v2 1/2] fs: fuse: Use strscpy instead of strcpy
Posted by Miquel Sabaté Solà 2 days, 9 hours ago
As pointed out in [1], strcpy() is deprecated in favor of
strscpy().

Furthermore, the length of the name to be copied is well known at this
point since we are going to move the pointer by that much on the next
line. Hence, it's safe to assume 'namelen' for the length of the string
to be copied.
