There are inconsistencies and some issues in marking functions as
notrace. On one hand, all inline functions are marked as "notrace" and
some libraries cannot be traced. At the same time, some functions should
not be traced but are not marked as notrace.

These patch address issues that I encountered during work on an
automatic tracing tool.

Nadav Amit (3):
  kprobes: Mark descendents of core_kernel_text as notrace
  lib/usercopy: Allow traceing of usercopy, xarray, iov_iter
  compiler: inline does not imply notrace
