The current algorithm for generating sub-context IDs is FILO. If the contexts are not closed in that order, the uniqueness of the ID will be compromised. I.e. logging the creation/deletion of context IDs with an application that assigns and closes in a FIFO order reveals: cache_id: assign: uctxt: 3 sub_ctxt: 0 cache_id: assign: uctxt: 3 sub_ctxt: 1 cache_id: assign: uctxt: 3 sub_ctxt: 2 cache_id: close: uctxt: 3 sub_ctxt: 0 cache_id: assign: uctxt: 3 sub_ctxt: 2 <<< The sub_ctxt ID 2 is reused incorrectly. Update the sub-context ID assign algorithm to use a bitmask of in_use contexts. The new algorithm will allow the contexts to be closed in any order, and will only re-use unused contexts. Size subctxt and subctxt_cnt to match the user API size. Reviewed-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Michael J.
