Hi all,
This patch series implements a new transport for 9pfs, aimed at Xen
systems.
The transport is based on a traditional Xen frontend and backend drivers
pair. This patch series implements the backend, which typically runs in
Dom0. I sent another series to implement the frontend in Linux
(http://marc.info/?l=linux-kernel&m=148883047125960&w=2).
The backend complies to the Xen transport for 9pfs specification
version 1, available here:
https://xenbits.xen.org/docs/unstable/misc/9pfs.html
Changes in v4:
- add reviewed-bys
- remove useless if(NULL) checks around g_free
- g_free g_malloc'ed sgs
- remove XEN_9PFS_RING_ORDER, make the ring order dynamic per ring,
reading the ring_order field in xen_9pfs_data_intf
- remove patch not to build Xen backends on non-Xen capable targets
because it is already upstream
Changes in v3:
- do not build backends for targets that do not support xen
- remove xen_9pfs.h, merge its content into xen-9p-backend.c
- remove xen_9pfs_header, introduce P9MsgHeader
- use le32_to_cpu to access P9MsgHeader fields
- many coding style fixes
- run checkpatch on all patches
- add check if num_rings < 1
- use g_strdup_printf
- free fsdev_id in xen_9pfs_free
- add comments
Changes in v2:
- fix coding style
- compile xen-9p-backend.c if CONFIG_XEN_BACKEND
- add patch to set CONFIG_XEN_BACKEND only for the right targets
- add review-bys
