This is needed for supporting multiple mount points. We can find out the device names to be used with mount by checking /sys/devices/virtio-pci/virtio*/device file if the device file have value 9 then the specific virtio device can be used for mounting. ex: #cat /sys/devices/virtio-pci/virtio1/device 9 now we can mount using # mount -t 9p -o trans=virtio virtio1 /mnt/ Signed-off-by: NAneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

Now that we have correct COMMIT semantics in writeback_single_inode, we can reduce and simplify nfs_wb_all(). Also replace nfs_wb_nocommit() with a call to filemap_write_and_wait(), which doesn't need to hold the inode->i_mutex. With that done, we can eliminate nfs_write_mapping() altogether.

This gives the filesystem more information about the writeback that is happening. Trond requested this for the NFS unstable write handling, and other filesystems might benefit from this too by beeing able to distinguish between the different callers in more detail.

Similar to the fsync issue fixed a while ago in commit 2daea67e we need to write for data to actually hit the disk before writing out the metadata to guarantee data integrity for filesystems that modify the inode in the data I/O completion path. Currently XFS and NFS handle this manually, and AFS has a write_inode method that does nothing but waiting for data, while others are possibly missing out on this. Fortunately this change has a lot less impact than the fsync change as none of the write_inode methods starts data writeout of any form by itself.
