Subject: clone: use kernel_ulong_t as type of flags parameter of unshare call
X-Git-Tag: v4.15~188

clone: use kernel_ulong_t as type of flags parameter of unshare call

Kernel declares flags parameter as long and looks like x32 and n32
implement no compat for this call.

* clone.c (SYS_FUNC(unshare)): Use getarg_ull and printflags64 for
obtaining and parsing flags parameter.
