ff207f9b2e Make __block_dev_get_elevator_name return const string 
Returning non-const char* doesn't have any benefits since
the only caller casts the output pointer to const char *.

This change fixes compilation on 5.3 kernel.

should be sufficient in IO path. When allocation buffers during

76acefd831 After loading cache mark used core ids. 
Since OCF doesn't use core and cache ids anymore adapter has to track occupied
ids on its own. After loading cache, ids of all loaded cores should be marked as
occupied, otherwise adding new core without explicit specifying core id will
fail.
