From: Md Haris Iqbal <haris.iqbal@xxxxxxxxxxxxxxx>
The kernel test robot triggerred the following warning,
>> drivers/block/rnbd/rnbd-clt.c:1397:42: warning: size argument in
'strlcpy' call appears to be size of the source; expected the size of the
destination [-Wstrlcpy-strlcat-size]
strlcpy(dev->pathname, pathname, strlen(pathname) + 1);
~~~~~~~^~~~~~~~~~~~~
To get rid of the above warning, use a kstrdup as Bart suggested.
Fixes: 64e8a6ece1a5 ("block/rnbd-clt: Dynamically alloc buffer for pathname & blk_symlink_name")
