    block: Improve zone reset execution · a2d6b3a2
    Damien Le Moal authored
    There is no need to synchronously execute all REQ_OP_ZONE_RESET BIOs
    necessary to reset a range of zones. Similarly to what is done for
    discard BIOs in blk-lib.c, all zone reset BIOs can be chained and
    executed asynchronously and a synchronous call done only for the last
    BIO of the chain.
    Modify blkdev_reset_zones() to operate similarly to
    blkdev_issue_discard() using the next_bio() helper for chaining BIOs. To
    avoid code duplication of that function in blk_zoned.c, rename
    next_bio() into blk_next_bio() and declare it as a block internal
    function in blk.h.
