Hi Jens, These are bcache patches for Linux v5.7-rc1. The major change is to make bcache btree check and dirty secrtors counting being multithreaded, then the registration time can be much less. My first four patches are for this purpose. Davidlohr Bueso contributes a patch to optimize barrier usage for atomic operations. By his inspiration I also compose a patch for the rested locations to change. Takashi Iwai contributes a helpful patch to avoid potential buffer overflow in bcache sysfs code path. Please take them, and thank you in advance.
