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 fs/aio.c | 8 +++++ fs/block_dev.c | 19 +++++++++++- fs/io_uring.c | 72 +++++++++++++++++++++++++++++++++++++++++-- include/linux/fs.h | 1 + include/uapi/linux/aio_abi.h | 1 + include/uapi/linux/io_uring.h | 8 ++++- 6 files changed, 105 insertions(+), 4 deletions(-) -- 2.7.4
