[PATCH 0/2] bcache fixes for Linux v5.13-rc6

[Coly Li]

Hi Jens,

This series is important for recent reported bcache panic partially
triggered by recent bio changes since Linux v5.12.

Current fix is 5th version since the first effort, it might not be
perfect yet, but it survives from different workloads from Rolf,
Thorsten and me for more than 1 week in total.

Considering many people are waiting for a stable enough fix and it is
kind of such fix. Please take them for Linux v5.13-rc6.

Thank you in advance for taking care of them.
