Subject: libmount: fix -Wunterminated-string-initialization warning
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74cef51bcb0bb9769fbe6a993fd59cda04b792e5;p=thirdparty%2Futil-linux.git

libmount: fix -Wunterminated-string-initialization warning

The "xx\0" string literal is 4 bytes but buf is only 3, truncating
the NUL terminator.  Since the buffer is immediately overwritten by
memcpy, just zero-initialize it instead.
