This patchset enables issuing zone-append using aio and io-uring direct-io interface.
For aio, this introduces opcode IOCB_CMD_ZONE_APPEND. Application uses start LBA of the zone to issue append. On completion 'res2' field is used to return zone-relative offset.
For io-uring, this introduces three opcodes: IORING_OP_ZONE_APPEND/APPENDV/APPENDV_FIXED. Since io_uring does not have aio-like res2, cqe->flags are repurposed to return zone-relative offset
Kanchan Joshi (1): aio: add support for zone-append
Selvakumar S (2): fs,block: Introduce IOCB_ZONE_APPEND and direct-io handling io_uring: add support for zone-append
