https://bugzilla.kernel.org/show_bug.cgi?id=208081 --- Comment #4 from Paolo Bonzini (bonzini@xxxxxxx) --- That patch won't work, most APFs have a node that comes from the stack. The issue must be arising when you enter this branch of kvm_async_pf_task_wake: /* * async PF was not yet handled. * Add dummy entry for the token. */ n = kzalloc(sizeof(*n), GFP_ATOMIC); but it should be handled here in kvm_async_pf_task_wait: if (e) { /* dummy entry exist -> wake up was delivered ahead of PF */ hlist_del(&e->link); raw_spin_unlock(&b->lock); kfree(e); return false; } -- You are receiving this mail because: You are watching the assignee of the bug.
