I tried to find vfs_mountroot operation in Linux and couldn't find it as p= art of vfsops. I believe that Linux doesn't have the vfs_mountroot as part of the vfsops. I am porting some BSD style code onto Linux and I ran into the issue and could not find an equivalent for vfs_mountroot operation. Any thoughts as to why Linux doesn't seem to have vfs_mountroot as part of = its vfsops Please share your thoughts as they are much valued are welcome. Thanks and Regards, Ronald
