vfsops:vfs_cmount

[Edward Tomasz Napierała]

Right now, most filesystems (probably every one except ZFS) implement
both xxx_mount() and xxx_cmount().  It looks like the former is used
to implement nmount(2), while the latter is used for mount(2).  Since
mount(8) already uses nmount(2), what about removing vfsops:vfs_cmount
implementations in filesystems?
