No need to parse the mount option into a structure before applying it to struct xfs_mount. The content of xfs_start_flags gets merged into xfs_parseargs. Calls inbetween don't care and can use mount members instead of the args struct. This patch uncovered that the mount option for shared filesystems wasn't ever exposed on Linux. The code to handle it is #if 0'ed in this patch pending a decision on this feature. I'll send a writeup about it to the list soon.
