Merge tag 'for-4.18/block-20180603' of git://git.kernel.dk/linux-block
Pull block updates from Jens Axboe: - clean up how we pass around gfp_t and blk_mq_req_flags_t (Christoph) - prepare us to defer scheduler attach (Christoph) - clean up drivers handling of bounce buffers (Christoph) - fix timeout handling corner cases (Christoph/Bart/Keith) - bcache fixes (Coly) - prep work for bcachefs and some block layer optimizations (Kent). - convert users of bio_sets to using embedded structs (Kent). - fixes for the BFQ io scheduler (Paolo/Davide/Filippo) - lightnvm fixes and improvements (Matias, with contributions from Hans and Javier) - adding discard throttling to blk-wbt (me) - sbitmap blk-mq-tag handling (me/Omar/Ming). - remove the sparc jsflash block driver, acked by DaveM. - Kyber scheduler improvement from Jianchao, making it more friendly wrt merging. - conversion of symbolic proc permissions to octal, from Joe Perches. Previously the block parts were a mix of both. - nbd fixes (Josef and Kevin Vigor) - unify how we handle the various kinds of timestamps that the block core and utility code uses (Omar) - three NVMe pull requests from Keith and Christoph, bringing AEN to feature completeness, file backed namespaces, cq/sq lock split, and various fixes - various little fixes and improvements all over the map * tag 'for-4.18/block-20180603' of git://git.kernel.dk/linux-block: (196 commits) blk-mq: update nr_requests when switching to 'none' scheduler block: don't use blocking queue entered for recursive bio submits dm-crypt: fix warning in shutdown path lightnvm: pblk: take bitmap alloc. out of critical section lightnvm: pblk: kick writer on new flush points lightnvm: pblk: only try to recover lines with written smeta lightnvm: pblk: remove unnecessary bio_get/put lightnvm: pblk: add possibility to set write buffer size manually lightnvm: fix partial read error path lightnvm: proper error handling for pblk_bio_add_pages lightnvm: pblk: fix smeta write error path lightnvm: pblk: garbage collect lines with failed writes lightnvm: pblk: rework write error recovery path lightnvm: pblk: remove dead function lightnvm: pass flag on graceful teardown to targets lightnvm: pblk: check for chunk size before allocating it lightnvm: pblk: remove unnecessary argument lightnvm: pblk: remove unnecessary indirection lightnvm: pblk: return NVM_ error on failed submission lightnvm: pblk: warn in case of corrupted write buffer ...
