The following patch is required to be patched in linux-5.10.y:

Commit 6b9dbedbe349 ("tty: fix deadlock caused by calling printk() under tty_port->lock")

was backported to linux-5.10.y. But __GFP_NOWARN flag is still not check in fail_dump(), and

deadlock issues still occur.

What about all of the other stable kernel trees that the tty patch was backported to? Do they also need the mm change as well? That would include 4.9.y, 4.14.y, 4.19.y, 5.4.y, 5.10.y, and 5.15.y.
