If the user of\ndpdk uses the symbol ENOENT as the judgment condition of\nthe return value, it may cause some abnormal phenomena\nin their own programs, such as when the mempool space is exhausted.\n\nFixes: ea5dd2744b90 (\"mempool: cache optimisations\")\n\nSigned-off-by: Zhiheng Chen <chenzhiheng0227@gmail.com>\n---\n lib/mempool/rte_mempool.h | 22 +++++++++++-----------\n 1 file changed, 11 insertions(+), 11 deletions(-)", "diff": "diff --git a/lib/mempool/rte_mempool.h b/lib/mempool/rte_mempool.h\nindex 1e7a3c1527..3b52bd6737 100644\n--- a/lib/mempool/rte_mempool.h\n+++ b/lib/mempool/rte_mempool.h\n@@ -737,8 +737,8 @@ rte_mempool_ops_alloc(struct rte_mempool *mp);\n * @param n\n * Number of objects to get.\n * @return\n- * - 0: Success; got n objects.\n- * - <0: Error; code of dequeue function.\n+ * - >=0: Success; number of objects supplied.\n+ * - -ENOBUFS: Not enough entries in the mempool; no object is retrieved.\n */\n static inline int\n rte_mempool_ops_dequeue_bulk(struct rte_mempool *mp,\n@@ -1453,7 +1453,7 @@ rte_mempool_put(struct rte_mempool *mp, void *obj)\n * A pointer to a mempool cache structure.
