Subject: tty/vt: Lockdep splat when Magic Sysrq SAK invoked

Hello all,

I get the following lockdep splat when I invoke the "ALT+SYSRQ+K"
combination on the keyboard. It usually happens the first time, but
doing it repeatedly always triggers it.

Kconfig follows splat.

Cheers,
Calvin

Calvin,

Thanks for this report. There is indeed a possibility of deadlock from
lock inversion here.

The VT driver is particularly uncareful regarding interface layering,
and often calls directly into internal tty functions which cause these
lock inversions.

At some point, the mess that is console_lock() needs to be addressed.
Unfortunately, there are few volunteers for such an undertaking.

Regards,
Peter Hurley

I know this is a year old but I believe this is fixed.

Could you confirm that you no longer can reproduce a lockdep report
invoking SAK on 3.12+?
