These changes allow\nthe aoe driver to handle network paths, or aoetgts, that are not working\nwell, compared to the others.\n\nPaths that do not get responses despite the retransmission of AoE\ncommands are marked as \"tainted\", and non-tainted paths are preferred.\n\nMeanwhile, the aoe driver attempts to \"probe\" the tainted path in the\nbackground by issuing reads of LBA 0 that are padded out to full\n(possibly jumbo-frame) size. If the probes get responses, then the path\nis \"redeemed\", and its taint is removed.\n\nThis mechanism has been shown to be helpful in transparently handling\nand recovering from real-world network \"brown outs\" in ways that the\nearlier \"shoot the help-needing target in the head\" mechanism could not.\n\nSigned-off-by: Ed Cashin \u003cecashin@coraid.com\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b91316f2b7bc0b1d128a9890a2a4895f7e1c74fc", "tree": "2e031c215e742fb3cde7f2cd41230318667ba1a1", "parents": [ "10935d052eef9441a551571ff5853f84a00b2fd4" ], "author": { "name": "Ed Cashin", "email": "ecashin@coraid.com", "time": "Mon Dec 17 16:04:06 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Dec 17 17:15:25 2012 -0800" }, "message": "aoe: return real minor number for static minors\n\nThe value returned by the static minor device number number allocator is\nthe real minor number, so it must be multiplied by the supported number\nof partitions per aoedev.\n\nWithout this fix the support for systems without udev is incomplete, and\nthe few users of aoe on such systems will have surprising results when\ndevice nodes names do not match the AoE target.\n\nSigned-off-by: Ed Cashin \u003cecashin@coraid.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "10935d052eef9441a551571ff5853f84a00b2fd4", "tree": "921ffe3962209af875358ee164dc6b3c62802f5c", "parents": [ "e0b2bbab0b569590e27161290f6ea549248356df" ], "author": { "name": "Ed Cashin", "email": "ecashin@coraid.com", "time": "Mon Dec 17 16:04:04 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Dec 17 17:15:25 2012 -0800" }, "message": "aoe: initialize sysminor to avoid compiler warning\n\nBecause the minor_get and related functions use the return values for\nerrors, the compiler doesn\u0027t know that sysminor will always either 1) be\ninitialized in aoedev_by_aoeaddr by the call to minor_get, or 2) be\nunused as the \"goto out\" is executed.\n\nThis patch avoids the compiler warning.\n\nSigned-off-by: Ed Cashin \u003cecashin@coraid.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e0b2bbab0b569590e27161290f6ea549248356df", "tree": "48525151e94b2206c6508b38ae978aabb7ead8ba", "parents": [ "60116cf77310c10b573552e4d700c270ddadba76" ], "author": { "name": "Ed Cashin", "email": "ecashin@coraid.com", "time": "Mon Dec 17 16:04:03 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Dec 17 17:15:25 2012 -0800" }, "message": "aoe: make error messages more specific in static minor allocation\n\nFor some special-purpose systems where udev isn\u0027t present, static\nallocation of minor numbers is desirable.
