Clean it up.\n\n1. end_that_request_data() is a thin wrapper around\n end_that_request_data_first() which checks whether bio is NULL\n before doing anything and handles bidi completion.\n blk_update_request() is a thin wrapper around\n end_that_request_data() which clears nr_sectors on the last\n iteration but doesn\u0027t use the bidi completion.\n\n Clean it up by moving the initial bio NULL check and nr_sectors\n clearing on the last iteration into end_that_request_data() and\n renaming it to blk_update_request(), which makes blk_end_io() the\n only user of end_that_request_data(). Collapse\n end_that_request_data() into blk_end_io().\n\n2. There are four visible completion variants - blk_end_request(),\n __blk_end_request(), blk_end_bidi_request() and end_request().\n blk_end_request() and blk_end_bidi_request() uses blk_end_request()\n as the backend but __blk_end_request() and end_request() use\n separate implementation in __blk_end_request() due to different\n locking rules.\n\n blk_end_bidi_request() is identical to blk_end_io(). Collapse\n blk_end_io() into blk_end_bidi_request(), separate out request\n update into internal helper blk_update_bidi_request() and add\n __blk_end_bidi_request(). Redefine [__]blk_end_request() as thin\n inline wrappers around [__]blk_end_bidi_request().\n\n3. As the whole request issue/completion usages are about to be\n modified and audited, it\u0027s a good chance to convert completion\n functions return bool which better indicates the intended meaning\n of return values.\n\n4. The function name end_that_request_last() is from the days when it\n was a public interface and slighly confusing. Give it a proper\n internal name - blk_finish_request().\n\n5. Add description explaning that blk_end_bidi_request() can be safely\n used for uni requests as suggested by Boaz Harrosh.\n\nThe only visible behavior change is from #1. nr_sectors counts are\ncleared after the final iteration no matter which function is used to\ncomplete the request. I couldn\u0027t find any place where the code\nassumes those nr_sectors counters contain the values for the last\nsegment and this change is good as it makes the API much more\nconsistent as the end result is now same whether a request is\ncompleted using [__]blk_end_request() alone or in combination with\nblk_update_request().\n\nAPI further cleaned up per Christoph\u0027s suggestion.\n\n[ Impact: cleanup, rq-\u003e*nr_sectors always updated after req completion ]\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\n" }, { "commit": "0b302d5aa7975006fa2ec3d66386610b9b36c669", "tree": "bba5de7b377ad167c4291cbdfd203ca7616d696d", "parents": [ "158dbda0068e63c7cce7bd47c123bd1dfa5a902c" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu Apr 23 11:05:18 2009 +0900" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Apr 28 07:37:34 2009 +0200" }, "message": "block: kill blk_end_request_callback()\n\nWith recent IDE updates, blk_end_request_callback() doesn\u0027t have any\nuser now.

There are only a couple of places which still do\nthis in kernel and converting to bio isn\u0027t difficult.\n\nThis patch converts ide-cd and atapi to use bio instead of rq-\u003edata\nfor request sense and internal pc commands. With previous change to\nunify sense request handling, this is relatively easily achieved by\nadding blk_rq_map_kern() during sense_rq prep and PC issue.\n\nIf blk_rq_map_kern() fails for sense, the error is deferred till sense\nissue and aborts the failed command which triggered the sense. Note\nthat this is a slim possibility as sense prep is done on each command\nissue, so for the above condition to actually trigger, all preps since\nthe last sense issue till the issue of the request which would require\na sense should fail.\n\n* do_request functions might sleep now. This should be okay as ide\n request_fn - do_ide_request() - is invoked only from make_request\n and plug work. Make sure this is the case by adding might_sleep()\n to do_ide_request().\n\n* Functions which access the read sense data before the sense request\n is complete now should access bio_data(sense_rq-\u003ebio) as the sense\n buffer might have been copied during blk_rq_map_kern().\n\n* ide-tape updated to map sg.\n\n* cdrom_do_block_pc() now doesn\u0027t have to deal with REQ_TYPE_ATA_PC\n special case. Simplified.\n\n* tp_ops-\u003eoutput/input_data path dropped from ide_pc_intr().\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n" }, { "commit": "068753203e6cd085664a62e0fc0636e19b148a12", "tree": "d3eec62f2ecd5524c89bb7c8d4f482e93a4cc196", "parents": [ "c457ce874a0f3dfa3d5e9f2309789f6f34e24325" ], "author": { "name": "Borislav Petkov", "email": "petkovbb@googlemail.com", "time": "Sun Apr 19 07:00:42 2009 +0900" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Apr 28 07:37:30 2009 +0200" }, "message": "ide-atapi: convert ide-{floppy,tape} to using preallocated sense buffer\n\nSince we\u0027re issuing REQ_TYPE_SENSE now we need to allow those types of\nrqs in the -\u003edo_request callbacks.
