But SCSI-ml treats discard requests as\nREQ_TYPE_BLOCK_PC.\n\nscsi-ml can handle discard requests as REQ_TYPE_FS\neasily. scsi_setup_discard_cmnd() sets up struct request and the bio\nnicely. Only remaining issue is that discard requests can\u0027t be\ncompleted partially so we need to modify sd_done.\n\nThis conversion also fixes the problem that discard requests aren\u0027t\nretried when possible (e.g. UNIT ATTENTION).\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n" }, { "commit": "8112586063fe53958d60218631d661533f304504", "tree": "7ee667fe782fe1c6b14fece28fbab5c3d24a0e4e", "parents": [ "b2a4a43dbaf10383703d512bbe560d5a24da0bf2" ], "author": { "name": "Stephen M.

Once the performant mode code was added, if the controller\ndoes not reset, it remains in performant mode. The code immediately\nafter the reset presumes the controller is in \"simple\" mode\n(which previously, it had remained in simple mode the whole time).\nIf the controller remains in performant mode any code which presumes\nit is in simple mode will not work. So the reset needs to be fixed.\n\nUnfortunately there are some controllers which cannot be reset by\neither method. (eg. p800). We detect these cases by noticing that\nthe controller seems to remain in performant mode even after a\nreset has been attempted. In those cases we ignore the controller,\nas any commands outstanding on it will result in stale completions.\nTo sum up, we try to do a better job of resetting the controller if\n\"reset_devices\" is set, and if it doesn\u0027t work, we ignore that\ncontroller.\n\nSigned-off-by: Stephen M.
