| Clark Williams | 2016-12-15 21:30:32 UTC | Doc Text | Cause: An upstream RT commit (fef016306919048a) was missed that made the DM system RT aware. The worker function dm_old_request_fn() was checking to ensure that irqs were disabled, but RT changes how preemption works with spinlocks so the check is invalid on RT. Consequence: Kernel panics on boot when dm-multipath module is loaded. Fix: Apply upstream RT commit fef016306919048a. This commit changes a BUG_ON macro to a BUG_ON_NONRT, which on RT becomes a noop. Result: No panic in when booting a kernel with dm-multipath module enabled. | |
