hw/9pfs: Add st_gen support in getattr reply
This patch use file system specific ioctl for getting i_generation value. Not all file system support the ioctl. So we add an export specific extended operation and assign right callback for the file system that support i_generation ioctl ["M. Mohan Kumar" <mohan@in.ibm.com> we can do ioctl only for regular files and directories on the server] Signed-off-by: Harsh Prateek Bora <harsh@linux.vnet.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
