  "message": "mempool: drop unnecessary and incorrect BUG_ON() from mempool_destroy()\n\nmempool_destroy() is a thin wrapper around free_pool().  The only thing it\nadds is BUG_ON(pool-\u003ecurr_nr !\u003d pool-\u003emin_nr).  The intention seems to be\nto enforce that all allocated elements are freed; however, the BUG_ON()\ncan\u0027t achieve that (it doesn\u0027t know anything about objects above min_nr)\nand incorrect as mempool_resize() is allowed to leave the pool extended\nbut not filled.  Furthermore, panicking is way worse than any memory leak\nand there are better debug tools to track memory leaks.\n\nDrop the BUG_ON() from mempool_destory() and as that leaves the function\nidentical to free_pool(), replace it.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
