Hi Pavel,

I have to breakdown In-Reply-To chain.

I can't see the message you sent above on lore, so I had to "lei up"
in order to get it. On lore, the patch series thread [1] displayed
is until [1001/1157], and rest of the thread (including yours) is skipped.
Actually, I can see your message from search results [2].

I guess why more than a thousand of patches must be reviewed for this
stable review cycle is because many of them (which have stable list CCed)
are errorneously submitted and merged for 6.0 merge window, not as
stabilization fixes for 5.19. But I also wonder if any of these patches
are not actually qualified for stable (new drivers?).

Thanks.
