  "message": "block: delete super ancient PC-XT driver for 1980\u0027s hardware\n\nThis driver was for the 8 bit ISA cards that were installed in\nthe PC-XT machines of 1980 vintage.  They supported the dual\nribbon cable MFM drives of 10-20MB capacity, and ran at a 3:1\ninterleave, giving performance on the order of 128kB/s.\n\nBy the introduction of the PC-AT (286) these controllers were\nalready scrapped in favour of 16 bit controllers with some onboard\nRAM that could support a 1:1 interleave.\n\nThe git history doesn\u0027t show any evidence of runtime fixes that\nwould reflect active usage; instead just the usual tree-wide API\ntype changes/cleanups.  Going back to in-source changelogs, the\nlast \"runtime\" fix that is evident is something I did over a\ndozen years ago[1] -- and even back then, the hardware was long\nsince unavailable, so that ancient fix was also not runtime tested.\n\nThe time is long overdue for this to get flushed, so lets get\nrid of it before anyone wastes more time doing builds and sparse\nchecks etc. on long since dead code.\n\n[1] http://lkml.indiana.edu/hypermail/linux/kernel/0102.2/0027.html\n\nSigned-off-by: Paul Gortmaker \u003cpaul.gortmaker@windriver.com\u003e\n",
