Subject: panic: Fix panic message visibility by calling bust_spinlocks(0) before dying
X-Git-Tag: v3.12-rc1~12569^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d014e8894dfc523dd9d2f2a17b6dcb94facea810;p=kernel%2Fkernel-generic.git

panic: Fix panic message visibility by calling bust_spinlocks(0) before dying

Commit ffd71da4e3f ("panic: decrease oops_in_progress only after
having done the panic") moved bust_spinlocks(0) to the end of the
function, which in practice is never reached.

As a result console_unblank() is not called, and on some systems
the user may not see the panic message.

Move it back up to before the unblanking.
