Hi,
I have a confusion regarding a struct data type in Ceph CRUSH source code.
Header fie in here
https://github.com/ceph/ceph/blob/master/src/crush/crush.h
If you see below. there is a struct data type namely _weight_set_. What I
have understood going through different CRUSH maps, this _weight_set_ array
should be a 2D array, am I right?
struct crush_choose_arg {
__s32 *ids; /*!< values to use instead of items */
__u32 ids_size; /*!< size of the __ids__ array */
struct crush_weight_set *weight_set; /*!< weight replacements for a given
position */
__u32 weight_set_positions;
};
