[Xen-devel] [PATCH v6 00/15] Argo: hypervisor-mediated interdomain communication

[Christopher Clark <christopher.w.clark@xxxxxxxxx>]

Posting an updated version (six) of this series with fixes for people
who are testing. Does not include changes for open discussion items.

Fixes include:

* Compat validation macros:
  - struct fields converted to use "struct form" in their declarations
  - dropped the overrides; using the struct validator rather than field
  - dropped the compat/argo.c file

* Notify op: indicates the "cannot queue a space available notification"
  condition via a flag to the caller instead of erroring the operation;
  enables the queries about other rings in the same op to continue.
  Reordered flags while there: static conditions first, errors last.

* Various fixes:
    - return EFAULT in sendv case of do_argo_op
    - WARN not ERR log level on encountering empty iovs
    - removed redundant bounds check in sendv vs MAX_ARGO_MESSAGE_SIZE
    - tabs for indentation in MAINTAINERS
    - added comment explaining tx_ptr rounding after iovs processing
    - BUILD_BUG_ON check for MAX_RING_SIZE align to PAGE_SIZE
    - use gprintk for error on denied registration of existing ring
