  "message": "dma-buf: system_heap: Use \u0027for_each_sgtable_sg\u0027 in pages free flow\n\nFor previous version, it uses \u0027sg_table.nent\u0027s to traverse sg_table in pages\nfree flow.\nHowever, \u0027sg_table.nents\u0027 is reassigned in \u0027dma_map_sg\u0027, it means the number of\ncreated entries in the DMA adderess space.\nSo, use \u0027sg_table.nents\u0027 in pages free flow will case some pages can\u0027t be freed.\n\nHere we should use sg_table.orig_nents to free pages memory, but use the\nsgtable helper \u0027for each_sgtable_sg\u0027(, instead of the previous rather common\nhelper \u0027for_each_sg\u0027 which maybe cause memory leak) is much better.\n\nFixes: d963ab0f15fb0 (\"dma-buf: system_heap: Allocate higher order pages if available\")\nSigned-off-by: Guangming \u003cGuangming.Cao@mediatek.com\u003e\nReviewed-by: Robin Murphy \u003crobin.murphy@arm.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e # 5.11.*\nReviewed-by: Christian König \u003cchristian.koenig@amd.com\u003e\nReviewed-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\nSigned-off-by: Sumit Semwal \u003csumit.semwal@linaro.org\u003e\nLink: https://patchwork.freedesktop.org/patch/msgid/20211126074904.88388-1-guangming.cao@mediatek.com\n",
