Hi Jens,

Here are the bcache patches for Linux v5.14.

The patches from Chao Yu and Ding Senjie are useful code cleanup. The
rested patches for the NVDIMM support to bcache journaling.

For the series to support NVDIMM to bache journaling, all reported
issue since last merge window are all fixed. And no more issue detected
during our testing or by the kernel test robot. If there is any issue
reported during they stay in linux-next, I, Jianpang and Qiaowei will
response and fix immediately.

Please take them for Linux v5.14.

Thank you in advance.
