Empty snapshot folder

Describe the problem you're observing

When browsing into the snapshot folder of a zfs filesystem, I can cd into the snapshot, but the folder has no contents. Mounting the same snapshot using mount -t zfs <snapshot_name> has the expected files

Describe how to reproduce the problem

-Create snapshot
-cd /.zfs/snapshot/
-ls
-mount -t zfs /mnt
-ls /mnt

Include any warning/errors/backtraces from the system logs

There are no errors/warnings to report. One other note, of which may be irrelevant, is that the filesystems I am testing this against are all derived from ZFS on root fs.

You may find an automount error in /proc/spl/kstat/zfs/dbgmsg. See my comments in #9461 and #9381.
I suspect this error occurs on systems with initramfs which chroot(2)s to new root filesystem and starts init process by running switch_root(8).

Ah, yes, you're correct... I tried searching for issues before posting so as not to duplicate, so apologies!
FWIW, I am receiving error 512 in the log... for instance

1583461577   zfs_ctldir.c:1086:zfsctl_snapshot_mount(): Unable to automount /new_root/var/lib/docker/.zfs/snapshot/autosnap_2020-02-29_00:00:08_daily error=512

Moving to #9461
