      "message": "block: Create bip slabs with embedded integrity vectors\n\nThis patch restores stacking ability to the block layer integrity\ninfrastructure by creating a set of dedicated bip slabs.  Each bip slab\nhas an embedded bio_vec array at the end.  This cuts down on memory\nallocations and also simplifies the code compared to the original bvec\nversion.  Only the largest bip slab is backed by a mempool.  The pool is\ncontained in the bio_set so stacking drivers can ensure forward\nprogress.\n\nSigned-off-by: Martin K.

      "message": "block: drop request-\u003ehard_* and *nr_sectors\n\nstruct request has had a few different ways to represent some\nproperties of a request.  -\u003ehard_* represent block layer\u0027s view of the\nrequest progress (completion cursor) and the ones without the prefix\nare supposed to represent the issue cursor and allowed to be updated\nas necessary by the low level drivers.  The thing is that as block\nlayer supports partial completion, the two cursors really aren\u0027t\nnecessary and only cause confusion.  In addition, manual management of\nrequest detail from low level drivers is cumbersome and error-prone at\nthe very least.\n\nAnother interesting duplicate fields are rq-\u003e[hard_]nr_sectors and\nrq-\u003e{hard_cur|current}_nr_sectors against rq-\u003edata_len and\nrq-\u003ebio-\u003ebi_size.  This is more convoluted than the hard_ case.\n\nrq-\u003e[hard_]nr_sectors are initialized for requests with bio but\nblk_rq_bytes() uses it only for !pc requests.  rq-\u003edata_len is\ninitialized for all request but blk_rq_bytes() uses it only for pc\nrequests.  This causes good amount of confusion throughout block layer\nand its drivers and determining the request length has been a bit of\nblack magic which may or may not work depending on circumstances and\nwhat the specific LLD is actually doing.\n\nrq-\u003e{hard_cur|current}_nr_sectors represent the number of sectors in\nthe contiguous data area at the front.  This is mainly used by drivers\nwhich transfers data by walking request segment-by-segment.  This\nvalue always equals rq-\u003ebio-\u003ebi_size \u003e\u003e 9.  However, data length for\npc requests may not be multiple of 512 bytes and using this field\nbecomes a bit confusing.\n\nIn general, having multiple fields to represent the same property\nleads only to confusion and subtle bugs.  With recent block low level\ndriver cleanups, no driver is accessing or manipulating these\nduplicate fields directly.  Drop all the duplicates.  Now rq-\u003esector\nmeans the current sector, rq-\u003edata_len the current total length and\nrq-\u003ebio-\u003ebi_size the current segment length.  Everything else is\ndefined in terms of these three and available only through accessors.\n\n* blk_recalc_rq_sectors() is collapsed into blk_update_request() and\n  now handles pc and fs requests equally other than rq-\u003esector update.\n  This means that now pc requests can use partial completion too (no\n  in-kernel user yet tho).\n\n* bio_cur_sectors() is replaced with bio_cur_bytes() as block layer\n  now uses byte count as the primary data length.\n\n* blk_rq_pos() is now guranteed to be always correct.  In-block users\n  converted.\n\n* blk_rq_bytes() is now guaranteed to be always valid as is\n  blk_rq_sectors().  In-block users converted.\n\n* blk_rq_sectors() is now guaranteed to equal blk_rq_bytes() \u003e\u003e 9.\n  More convenient one is used.\n\n* blk_rq_bytes() and blk_rq_cur_bytes() are now inlined and take const\n  pointer to request.\n\n[ Impact: API cleanup, single way to represent one property of a request ]\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"
