[PATCH V8 0/9] nvmet: add ZBD backend support

Hi,
NVMeOF Host is capable of handling the NVMe Protocol based Zoned Block
Devices (ZBD) in the Zoned Namespaces (ZNS) mode with the passthru
backend. There is no support for a generic block device backend to
handle the ZBD devices which are not NVMe protocol compliant.
This adds support to export the ZBDs (which are not NVMe drives) to host
the from target via NVMeOF using the host side ZNS interface.
The patch series is generated in bottom-top manner where, it first adds
prep patch and ZNS command-specific handlers on the top of genblk and
updates the data structures, then one by one it wires up the admin cmds
in the order host calls them in namespace initializing sequence. Once
everything is ready, it wires-up the I/O command handlers. See below for
patch-series overview.
All the testcases are passing for the ZoneFS where ZBD exported with
NVMeOF backed by null_blk ZBD and null_blk ZBD without NVMeOF. Adding
test result below.
Note: This patch-series is based on the earlier posted patch series :-
[PATCH 0/4] nvmet: admin-cmd related cleanups and a fix
http://lists.infradead.org/pipermail/linux-nvme/2021-January/021729.html
-ck
Changes from V7:-
1. Just like what block layer provides an API for bio_init(), provide
nvmet_bio_init() such that we move bio initialization code for
nvme-read-write commands from bdev and zns backend into the centralize
helper.
2. With bdev/zns/file now we have three backends that are checking for
req->sg_cnt and calling nvmet_check_transfer_len() before we process
nvme-read-write commands. Move this duplicate code from three
backeneds into the helper.
3. Export and use nvmet_bio_done() callback in
nvmet_execute_zone_append() instead of the open coding the function.
This also avoids code duplication for bio & request completion with
error log page update.
4. Add zonefs tests log for dm linear device created on the top of SMR HDD
exported with NVMeOF ZNS backend with the help of nvme-loop.
Changes from V6:-
1. Instead of calling report zones to find conventional zones in the
loop use the loop inside LLD blkdev_report_zones()->LLD_report_zones,
that also simplifies the report zone callback.
2. Fix the bug in nvmet_bdev_has_conv_zones().
3. Remove conditional operators in the nvmet_bdev_execute_zone_append().
Changes from V5:-
1. Use bio->bi_iter.bi_sector for result of the REQ_OP_ZONE_APPEND
command.
2. Add endianness to the helper nvmet_sect_to_lba().
3. Make bufsize u32 in zone mgmt recv command handler.
4. Add __GFP_ZERO for report zone data buffer to return clean buffer.
Changes from V4:-
1. Don't use bio_iov_iter_get_pages() instead add a patch to export
bio_add_hw_page() and call it directly for zone append.
2. Add inline vector optimization for append bio.
3. Update the commit logs for the patches.
4. Remove ZNS related identify data structures, use individual members.
5. Add a comment for macro NVMET_MPSMIN_SHIFT.
6. Remove nvmet_bdev() helper.
7. Move the command set identifier code into common code.
8. Use IS_ENABLED() and move helpers fomr zns.c into common code.
9. Add a patch to support Command Set identifiers.
10. Open code nvmet_bdev_validate_zns_zones().
11. Remove the per namespace min zasl calculation and don't allow
namespaces with zasl value > the first ns zasl value.
12. Move the stubs into the header file.
13. Add lba to/from sector conversion helpers and update the
io-cmd-bdev.c to avoid the code duplication.
14. Add everything into one patch for zns command handlers and
respective calls from the target code.
15. Remove the trim ns-desclist admin callback patch from this series.
16. Add bio get and put helpers patches to reduce the duplicate code in
generic bdev, passthru, and generic zns backend.
Changes from V3:-
1. Get rid of the bio_max_zasl check.
2. Remove extra lines.
4. Remove the block layer api export patch.
5. Remove the bvec check in the bio_iov_iter_get_pages() for
REQ_OP_ZONE_APPEND so that we can reuse the code.
Changes from V2:-
1. Move conventional zone bitmap check into
nvmet_bdev_validate_zns_zones().
2. Don't use report zones call to check the runt zone.
3. Trim nvmet_zasl() helper.
4. Fix typo in the nvmet_zns_update_zasl().
5. Remove the comment and fix the mdts calculation in
nvmet_execute_identify_cns_cs_ctrl().
6. Use u64 for bufsize in nvmet_bdev_execute_zone_mgmt_recv().
7. Remove nvmet_zones_to_desc_size() and fix the nr_zones
calculation.
8. Remove the op variable in nvmet_bdev_execute_zone_append().
9. Fix the nr_zones calculation nvmet_bdev_execute_zone_mgmt_recv().
10. Update cover letter subject.
Changes from V1:-
1. Remove the nvmet-$(CONFIG_BLK_DEV_ZONED) += zns.o.
2. Mark helpers inline.
3. Fix typos in the comments and update the comments.
4. Get rid of the curly brackets.
5. Don't allow drives with last smaller zones.
6. Calculate the zasl as a function of ax_zone_append_sectors,
bio_max_pages so we don't have to split the bio.
7. Add global subsys->zasl and update the zasl when new namespace
is enabled.
8. Rmove the loop in the nvmet_bdev_execute_zone_mgmt_recv() and
move functionality in to the report zone callback.
9. Add goto for default case in nvmet_bdev_execute_zone_mgmt_send().
10. Allocate the zones buffer with zones size instead of bdev nr_zones.
