  "message": "libata: automatically use DMADIR if drive/bridge requires it\n\nBack in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir.\n\nThat\u0027s nice, but most SATA devices which need it will tell us about it\nin their IDENTIFY PACKET response, as bit-15 of word-62 of the\nreturned data (as per ATA7, ATA8 specifications).\n\nSo for those which specify it, we should automatically use the DMADIR bit.\nOtherwise, disc writing will fail by default on many SATA-ATAPI drives.\n\nThis patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it\nif atapi_dmadir is set or identify data indicates DMADIR is necessary.\natapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting\nDMADIR.\n\nOriginal patch is from Mark Lord.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nCc: Mark Lord \u003cmlord@pobox.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n",
