Description

We seem to be getting periodic outbreaks of messages that reads like this "format at cl_io.c:1551:cl_req_page_add doesn't end in newline" on console during testing.

Finally I had enough and dug a bit into it, the culprit is osc-page printing, because the message printed gets pretty long and overflows 255 bytes of allowed space (LU_CDEBUG_LINE).
