Hi Jarkko,

Here's a patch to add some tracepoints to keyrings to make it easier to
debug what's going on, plus a bunch of preliminary patches to move things
about a bit to make that easier.

The patches can also be found here:

Thanks,
David

David Howells (7):
  keys: Out of line key_is_dead() so it can have tracepoints added in
  keys: Extract struct key_user to its own header for tracing purposes
  keys: Move key_get() out of line so a tracepoint can be added
  keys: Add a key_ref_get() wrapper
  keys: Use key_get() instead of __key_get()
  keys: Provide a key_try_get() function and use it
  keys: Add tracepoints for the keyrings facility
