Since this is in a chroot, samba cannot examine its mount options
directly through /proc/self/mount*, does this make a difference? Do I
need to create a mount namespace when running the testsuite in a chroot?

What it can see is:
$ /proc/self/mountinfo 
366 116 254:5 /ondra/repos /mnt/repos ro,relatime shared:63 - ext4 /dev/mapper/ixos--vg-home rw,commit=600
379 116 0:4 / /proc rw,relatime shared:208 - proc proc rw

With the chroot being stored in /home:
16 27 254:5 / /home rw,relatime shared:63 - ext4 /dev/mapper/ixos--vg-home rw,commit=600

```
cat /proc/fs/ext4/dm-5/options
rw
bsddf
nogrpid
block_validity
dioread_lock
nodiscard
delalloc
nowarn_on_error
journal_checksum
barrier
auto_da_alloc
user_xattr
acl
noquota
resuid=0
resgid=0
errors=continue
commit=600
min_batch_time=0
max_batch_time=15000
stripe=0
data=ordered
inode_readahead_blks=32
init_itable=10
max_dir_size_kb=0
```
