Subject: [PATCH] block: Add handling for zone append command in
blk_complete_request
Git-commit: a12821d5e012a42673f6fe521971f193441d8aa4
Patch-mainline: v5.17-rc5
References: jsc#PED-1183
Zone append command needs special handling to update the bi_sector
field in the bio struct with the actual position of the data in the
device. It is stored in __sector field of the request struct.
Fixes: 5581a5ddfe8d ("block: add completion handler for fast path")
