C++ (Cpp) find_syscall_meta Examples

Example #1

File: trace_syscalls.c Project: mb3dot/community-b3-kernel

int __init init_ftrace_syscalls(void)
{
	struct syscall_metadata *meta;
	unsigned long addr;
	int i;

					NR_syscalls, GFP_KERNEL);
	if (!syscalls_metadata) {

		meta = find_syscall_meta(addr);
		if (!meta)
			continue;

		meta->syscall_nr = i;
		syscalls_metadata[i] = meta;
	}

	return 0;
}
