nvme-core: remove extra condition for vwc

2020-10-07T05:56:20Z

In nvme_set_queue_limits() we initialize vwc to false and later add a condition to set vwc true. The value of the vwc can be declare initialized which makes all the blk_queue_XXX() calls uniform. Signed-off-by: Chaitanya Kulkarni Reviewed-by: Keith Busch Signed-off-by: Christoph Hellwig

nvme-core: remove extra variable

2020-10-07T05:56:20Z

In nvme_validate_ns() the exra variable ctrl is used only twice. Using ns->ctrl directly still maintains the redability and original length of the lines in the code. Get rid of the extra variable ctrl & use ns->ctrl directly. Signed-off-by: Chaitanya Kulkarni Signed-off-by: Christoph Hellwig

nvme: remove nvme_identify_ns_list

nvme: refactor nvme_validate_ns

2020-10-07T05:56:19Z

Move the logic to revalidate the block_device size or remove the namespace from the caller into nvme_validate_ns. This removes the return value and thus the status code translation. Additionally it also catches non-permanent errors from nvme_update_ns_info using the existing logic. Signed-off-by: Christoph Hellwig Reviewed-by: Keith Busch Reviewed-by: Damien Le Moal

nvme: move nvme_validate_ns

2020-10-07T05:56:19Z

nvme: query namespace identifiers before adding the namespace

2020-10-07T05:56:19Z

Check the namespace identifier list first thing when scanning namespaces. This keeps the code to query the CSI common between the alloc and validate path, and helps to structure the code better for multiple command set support.
