Hi Martin,

This patch series fixes a recently reported use-after-free in the SRP driver.
Please consider this patch series for kernel v5.20.

Changes compared to v3:
- Added a patch to delay scsi_remove_target() until dependent devices have been
  removed.
- Split a patch into two patches.

Changes compared to v2:
- Dropped the patch that simplifies scsi_forget_host().
- Replaced patch 2/3 with a patch from Ming Lei.

Changes compared to v1:
- Expanded this series from one to three patches.
- Fixed the description of patch 3/3.

Bart Van Assche (2):
  scsi: core: Make sure that targets outlive devices
  scsi: core: Call blk_mq_free_tag_set() earlier

Ming Lei (2):
  scsi: core: Make sure that hosts outlive targets
  scsi: core: Simplify LLD module reference counting
