    They provide no information to the human reader, but they tell klogd
    (and other tools) that the enclosed value is a kernel address that
    should be looked up in the System.map file and decoded into name +
    offset.

Of course. But since there is no information in [< >]
(their presence is syntactically determined, not semantically)
the tools you mention can be trivially patched to work without
this [< >] kludge. On the other hand, when the system panics
often klogd and similar nice programs do not run at all, and
hence are unable to do any good. All information available
is the information on the screen, and it is really a pity
to lose EIP and get a few parentheses instead.
