Subject: ujail: don't pass unused arg in clone call
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fprocd.git;a=commitdiff_plain;h=f35fa23a126505a726a9f09be01cd351a08e2532;hp=34a53406063495710e2416da3bdc40f80a72963c

ujail: don't pass unused arg in clone call

clone() call need a function with "void *" arg
(else we have a compilation error)
