Subject: [PATCH v5 0/3] implement direct IO with integrity
Date: Tue, 20 Sep 2022 17:46:15 +0300 [thread overview]
Message-ID: <[email protected]> (raw)
This series of patches makes possible to do direct block IO
with integrity payload using io uring kernel interface.
Userspace app can utilize new READV_PI/WRITEV_PI operation with a new
fields in sqe struct (pi_addr/pi_len) to provide iovec's with
integrity data.
Changes since v4:
- fixed sparse warnings reported by robot
- some litle code sync rw.c -> rw_pi.c
- some includes cleanup
Changes since v3:
- fixed warnings reported by robot
Changes since v2:
- separate code from fast path
- keep rw_pi struct size <= 64 byte
- using kiocb->private pointer to pass
PI data iterator to block direct IO layer
- improved bio_integrity_add_iovec function
