This is a well-motivated, straightforward optimization series. The core idea — avoiding a redundant `static_branch_unlikely()` evaluation at guarded tracepoint call sites — is sound and was explicitly requested by Peter Zijlstra and Steven Rostedt. The implementation is clean: patch 1 adds the new API in three locations within `tracepoint.h`, and the remaining patches are mechanical conversions.
The mbox filtered to dri-devel contains the cover letter (0/19) plus patches 1/19, 5/19, 8/19, and 10/19. The conversion patches are straightforward and correct. I have one concern about the API patch regarding the LOCKDEP assertion, and one minor observation about the commit message.
