Incidentally, bpf_obj_get_user()/bpf_obj_do_get() should just use user_path(), rather than wanking with getname()+kern_path(pname->name)+putname(). Note that kern_path() will do getname_kernel() to get struct pathname... Would cause problems for tracepoints in there, though. And that, BTW, is precisely why I don't want tracepoints in core VFS, TYVM - makes restructuring the code harder...
