[ Upstream commit e7508d48565060af5d89f10cb83c9359c8ae1310 ]
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.
