Author: Jakub Kicinski Date: Thu Jan 5 22:33:54 2023 -0800 devlink: bump the instance index directly when iterating xa_find_after() is designed to handle multi-index entries correctly. If a xarray has two entries one which spans indexes 0-3 and one at index 4 xa_find_after(0) will return the entry at index 4. Having to juggle the two callbacks, however, is unnecessary in case of the devlink xarray, as there is 1:1 relationship with indexes. Always use xa_find() and increment the index manually.
