* RBD: compare-and-write operation is no longer limited to 512-byte sectors.
Assuming proper alignment, it now allows operating on stripe units (4M by
default).
+* RBD: New `rbd_aio_compare_and_writev` API method to support scatter/gather
+ on both compare and write buffers. This compliments existing `rbd_aio_readv`
+ and `rbd_aio_writev` methods.
* The 'AT_NO_ATTR_SYNC' macro is deprecated, please use the standard 'AT_STATX_DONT_SYNC'
macro. The 'AT_NO_ATTR_SYNC' macro will be removed in the future.
