Subject: [PATCH 0/3] zone-append support in aio and io-uring
Date: Wed, 17 Jun 2020 22:53:36 +0530	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: CGME20200617172653epcas5p488de50090415eb802e62acc0e23d8812@epcas5p4.samsung.com

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
