This patch set attempts to optimize the parallelism of SMC-R connections,
mainly to reduce unnecessary blocking on locks, and to fix exceptions that
occur after thoses optimization.


D. Wythe (10):
   net/smc: Fix potential panic dues to unprotected
     smc_llc_srv_add_link()
   net/smc: fix application data exception
   net/smc: fix SMC_CLC_DECL_ERR_REGRMB without smc_server_lgr_pending
   net/smc: remove locks smc_client_lgr_pending and
     smc_server_lgr_pending
   net/smc: allow confirm/delete rkey response deliver multiplex
   net/smc: make SMC_LLC_FLOW_RKEY run concurrently
   net/smc: llc_conf_mutex refactor, replace it with rw_semaphore
   net/smc: use read semaphores to reduce unnecessary blocking in
     smc_buf_create() & smcr_buf_unuse()
   net/smc: reduce unnecessary blocking in smcr_lgr_reg_rmbs()
   net/smc: replace mutex rmbs_lock and sndbufs_lock with rw_semaphore

Hi Jan and Wenjia,

I'm wondering whether the bug fix patches need to be put together in this series. I'm considering sending these bug fix patches separately now, which may be better, in case that our patch might have other problems. These bug fix patches are mainly independent, even without my other
patches, they may be triggered theoretically.

Hi D.

Wenjia and i just talked about that. For us it would be better separating the fixes and the new logic.
If the fixes are independent feel free to post them to net.


Of course, these bug fix patches may need to ahead before the other PATCH,
otherwise the probability of the problems they fixed may be amplified in
an intermediate version.

True. Thanks for pointing that out.

Thank you
- Jan

What do you think?

Best Wishes.
D. Wythe
