Subject: bjm: use getarg_ull for retrieving first two parameters of init_module syscall
X-Git-Tag: v4.15~198
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=dad07434a85f2132c412c95cde4011157857df91;p=strace

bjm: use getarg_ull for retrieving first two parameters of init_module syscall

As init_module has no compat wrapper, its first parameter is a pointer
and the second is length, they both have the same size as kernel_ulong_t
type.

* bjm.c (SYS_FUNC(init_module)): Obtain first two parameters using
getarg_ull, print address argument using printaddr_ull, print length
argument using "%llu" conversion specifier.
