Subject: [PATCH v3 0/2] bcache: fix I/O accounting leak

From: Shida Zhang <zhangshida@...inos.cn>

This series addresses an I/O accounting leak where detached bcache
devices could report 100% utilization in iostat after completion
of discard requests.

Changes since v2:
- Omitting the dead NULL check for bio_alloc_clone() (suggested by hch).
- Updated the Fixes tag for the accounting leak.

Shida Zhang (2):
  bcache: remove dead code in detached_dev_do_request
  bcache: fix I/O accounting leak in detached_dev_do_request
