Hey Nic,
So here are a couple of fixes for iSER target DIF on top of latest
for-next for 3.15.
Patch #1 fixes suppressed completions for REG_SIG_MR work requests.
Patch #2 fixes accounting of post_send_buf_count when RDMA_READs may
get a completion (required in the DIF case).
Patch #3 moves the DIF status check to a function to avoid code
duplication (was fixed before but I'm not sure where it got lost).
Patch #4 adds the protection-passthrough-only mode that we agreed on
for loopback/vhost_scsi transports.
This set survived a couple of hours of:
- Stress IO (with/without DIF)
- Live target shutdown & resume (during traffic)
- Login/Logout
I can try and split Patch #2 if you want to squash it in.
Sagi Grimberg (4):
Target/iser: Fix signature work requests accounting
Target/iser: Consider DIF and RDMA_READ completions when calculating
post_send counter
Target/iser: Move check signature status to a function
Target/dif: Introduce protection-passthough-only mode
