Hi-
This is a Request For Comments.
Oracle has an interest in a common observability infrastructure in
the RDMA core and ULPs. One alternative for this infrastructure is
to introduce static tracepoints that can also be used as hooks for
eBPF scripts, replacing infrastructure that is based on printk.
As an addendum to tracepoints already in NFS/RDMA and parts of the
RDMA core, this series takes that approach as a strawman. Feedback
is welcome!
