tracing fixes for v6.7-rc7:
- Fix readers that are blocked on the ring buffer when buffer_percent is 100%. They are supposed to wake up when the buffer is full, but because the sub-buffer that the writer is on is never considered "dirty" in the calculation, dirty pages will never equal nr_pages. Add +1 to the dirty count in order to count for the sub-buffer that the writer is on. - When a reader is blocked on the "snapshot_raw" file, it is to be woken up when a snapshot is done and be able to read the snapshot buffer. But because the snapshot swaps the buffers (the main one with the snapshot one), and the snapshot reader is waiting on the old snapshot buffer, it was not woken up (because it is now on the main buffer after the swap). Worse yet, when it reads the buffer after a snapshot, it's not reading the snapshot buffer, it's reading the live active main buffer. Fix this by forcing a wakeup of all readers on the snapshot buffer when a new snapshot happens, and then update the buffer that the reader is reading to be back on the snapshot buffer. - Fix the modification of the direct_function hash. There was a race when new functions were added to the direct_function hash as when it moved function entries from the old hash to the new one, a direct function trace could be hit and not see its entry. This is fixed by allocating the new hash, copy all the old entries onto it as well as the new entries, and then use rcu_assign_pointer() to update the new direct_function hash with it. This also fixes a memory leak in that code. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZZAzTxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qs9IAP9e6wZ74aEjMED9nsbC49EpyCNTqa72 y0uDS/p9ppv52gD7Be+l+kJQzYNh6bZU0+B19hNC2QVn38jb7sOadfO/1Q8= =NDkf -----END PGP SIGNATURE----- Merge tag 'trace-v6.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix readers that are blocked on the ring buffer when buffer_percent is 100%.
