Add systrace_linux32 and systrace_freebsd32 modules which provide support for tracing compat system calls in addition to native system call tracing provided by systrace module. Provided that all the systrace modules are loaded now you can select what syscalls to trace in the following manner: syscall::xxx:yyy - work on all system calls that match the specification syscall:freebsd:xxx:yyy - only native system calls syscall:linux32:xxx:yyy - linux32 compat system calls syscall:freebsd32:xxx:yyy - freebsd32 compat system calls on amd64 PR: kern/152822 Submitted by: Artem Belevich <fbsdlist@src.cx> Reviewed by: jhb (earlier version) MFC after: 3 weeks
