[Xen-devel] [PATCH v7 0/4] new ring macros, 9pfs and pvcalls headers

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

this patch series introduces a set of new ring macros to support rings
in the formats specified by the Xen 9pfs transport and PV Calls
protocol. It also introduces the Xen 9pfs and PV Calls protocols
headers.

Changes in v7:
- code style
- remove -include from prereq variable
- use only one prereq variable for both cxx and c99

Changes in v6:
- remove stray semicolons
- code style fix for return statements
- make the last element of DEFINE_XEN_FLEX_RING non a static inline
  function
- improve ring.h prereq comment
- remove mask_order
- use ring_size as parameter instead of ring_order
- fix indentation of parameters in ring.h
- improve order of parameters in ring.h
- introduce per header prereqs in xen/include/Makefile

Changes in v5:
- parenthesize uses of macro parameters in XEN_FLEX_RING_SIZE
- add grant_table.h to the list of prereqs in ring.h and remove the
  #include from ring.h
- #include grant_table.h in 9pfs.h and pvcalls.h
- remove PAGE_SHIFT definition, define XEN_PAGE_SHIFT instead
- code style fixes
- remove struct xen_9pfs_header definition
- don't add extra -include cstring to all c++ tests, only when needed
- add headers99.chk to .gitignore 

Changes in v4:
- include ../grant_table.h in ring.h
- add a comment about required declarations on top of ring.h
- add a patch to introduce a C99 headers check
- add -include string.h to the existing C++ headers check
- add 9pfs and pvcalls to the C99 headers check

Changes in v3:
- fix commit message
- add newlines after read/write_packet functions
- reorder DEFINE_XEN_FLEX_RING_AND_INTF and DEFINE_XEN_FLEX_RING

Changes in v2:
- replace __attribute__((packed)) with #pragma pack
- remove XEN_9PFS_RING_ORDER, the 9pfs ring order should be dynamic
- add editor configuration blocks
- add links to the specs


Stefano Stabellini (4):
      ring.h: introduce macros to handle monodirectional rings with multiple 
req sizes
      xen: introduce a C99 headers check
      Introduce the Xen 9pfs transport header
      Introduce the pvcalls header
