Subject[PATCH 0/3] zone-append support in aio and io-uring
Date
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
