Linus Torvalds 151647ab58 Locking changes for v6.11: 
- Jump label fixes, including a perf events fix that originally
    manifested as jump label failures, but was a serialization bug
    at the usage site.
 
  - Mark down_write*() helpers as __always_inline, to improve
    WCHAN debuggability.
 
  - Misc cleanups and fixes.
