Add a helper to insert a bio into a bio_list so that the list remains sorted by bi_sector. While it is on the upper hand of the size for an inline function, it is a trade off for having it with the common helpers, but not bloating the kernel unless the so far only user is enabled. If it gets more widely used moving it out of line should be considered. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Damien Le Moal <dlemoal@kernel.org>
This instructs the zone write plugging code to queue up any bio not at the write pointer, and includes an implicit guarantee that the caller will fill any sector gaps. I.e., this can be used by file systems and stacking block drivers, but not for untrusted user block device writes. Because all writes through the write plug cancel all outstanding writes for the plug there is no risk that queue up writes for higher sectors are stuck in the zone write plug even on error. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Damien Le Moal <dlemoal@kernel.org>
Use the new REQ_ZWPLUG_UNORDERED bio flag so that even copies to sequential write required zones can queue up writes bios as soon as the reads finish. This simplifies the code and reduces the submission latency as all writes are immediately available in the zoned write plug list when the previous write completes instead of going through two layers of queueing.
