Andriy Gapon d092f79489 zfs_get_vfs: reference a requested filesystem instead of vfs_busy-ing it ... The only consumer of zfs_get_vfs, zfs_unmount_snap, does not need the filesystem to be busy, it just need a reference that it can pass to dounmount. Also, previously the code was racy as it unbusied the filesystem before taking a reference on it. Now the code should be simpler and safer.
