Subject: [PATCH 0/2] Fix lock errors in VDUSE suspend feature
Date: Thu, 11 Jun 2026 15:38:04 +0200	[thread overview]
Message-ID: <20260611133806.198402-1-eperezma@redhat.com> (raw)

Fix wrong ordering at taking semaphore after spinlock and convert the spinlock
take and release into guards, so they are not lost after a return.

This series goes on top of https://lore.kernel.org/lkml/20260610083452.477759-1-eperezma@redhat.com/

It would be great if these can be squashed.

  vduse: fix not releasing taken semaphore in vduse_dev_queue_irq_work
  vduse: not take the device semaphore while holding vq spinlock
