[PATCH v3 0/2] block: enable per-cpu bio cache by default

[Fengnan Chang]

For now, per-cpu bio cache was only used in the io_uring + raw block
device, filesystem also can use this to improve performance.
After discussion in [1], we think it's better to enable per-cpu bio cache
by default.

v3:
fix some build warnings.

v2:
enable per-cpu bio cache for passthru IO by default.

v1:
