Description

Format 2 images with the STRIPINGV2 feature bit set (created with rbd create --stripe-count X --stripe-unit Y --order Z --format 2 pool/image) use more generalized striping with the same parameters as cephfs. These are especially useful for small sequential write workloads like database write-ahead logs.

The first thing to do is get the kernel to read the additional striping information from the header if STRIPINGV2 is enabled.
