Synopsis: ffs_snapshot_read -> uvm_fault (or pool page empty) doing dump/restore with snapshot State-Changed-From-To: open->needs-pullups State-Changed-By: [email protected] State-Changed-When: Fri, 31 Jul 2026 16:03:31 +0000 State-Changed-Why: Great, sounds like the mechanism of the deadlock is understood now, so let's get this pulled up to 9, 10, and 11. Sounds like ptyfs will avoid this problem for ssh, but without the patch, revoke -- whether done explicitly by user programs, or in the kernel when logging out of a non-pty tty -- will still trigger the deadlock.
