- * XXX - UGLY HACK
- *
- * The block layer suspend/resume path is fundamentally broken due
- * to freezable kthreads and workqueue and may deadlock if a block
- * device gets removed while resume is in progress. I don't know
- * what the solution is short of removing freezable kthreads and
- * workqueues altogether.
- *
- * The following is an ugly hack to avoid kicking off device
- * removal while freezer is active. This is a joke but does avoid
- * this particular deadlock scenario.
