I agree, the profiling part is the sweet spot. Profiling should be in, probably even selectable at runtime as opposed to a config-switch. This way we could have it in enterprise distros that would'nt build another kernel image for this.The profiling code has certainly been useful to you during development,
and you should keep that code around for your own work on it,
but maybe you should not push that upstream, because regular users
are not going to need it.
Nope. Profiling is absolutely fundamental to how AXFS works. Read
the [PATCH 00/10] thread again.
