  Tracing fixes for 6.5:

- Fix to /sys/kernel/tracing/per_cpu/cpu*/stats read and entries.
  If a resize shrinks the buffer it clears the read count to notify
  readers that they need to reset. But the read count is also used for
  accounting and this causes the numbers to be off. Instead, create a
  separate variable to use to notify readers to reset.

- Fix the ref counts of the "soft disable" mode. The wrong value was
  used for testing if soft disable mode should be enabled or disable,
  but instead, just change the logic to do the enable and disable
  in place when the SOFT_MODE is set or cleared.

- Several kernel-doc fixes

- Removal of unused external declarations
