  "message": "block: Consolidate bio_alloc_bioset(), bio_kmalloc()\n\nPreviously, bio_kmalloc() and bio_alloc_bioset() behaved slightly\ndifferent because there was some almost-duplicated code - this fixes\nsome of that.\n\nThe important change is that previously bio_kmalloc() always set\nbi_io_vec \u003d bi_inline_vecs, even if nr_iovecs \u003d\u003d 0 - unlike\nbio_alloc_bioset(). This would cause bio_has_data() to return true; I\ndon\u0027t know if this resulted in any actual bugs but it was certainly\nwrong.\n\nbio_kmalloc() and bio_alloc_bioset() also have different arbitrary\nlimits on nr_iovecs - 1024 (UIO_MAXIOV) for bio_kmalloc(), 256\n(BIO_MAX_PAGES) for bio_alloc_bioset(). This patch doesn\u0027t fix that, but\nat least they\u0027re enforced closer together and hopefully they will be\nfixed in a later patch.\n\nThis\u0027ll also help with some future cleanups - there are a fair number of\nfunctions that allocate bios (e.g. bio_clone()), and now they don\u0027t have\nto be duplicated for bio_alloc(), bio_alloc_bioset(), and bio_kmalloc().\n\nSigned-off-by: Kent Overstreet \u003ckoverstreet@google.com\u003e\nCC: Jens Axboe \u003caxboe@kernel.dk\u003e\nv7: Re-add dropped comments, improv patch description\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n",
