What's your mount option and mkfs option on those two partitions, and what's
your kernel version?
I checked the code, only place where we give 'not supported' is as below
by checking whether underlying device supports discard.
f2fs_ioc_fitrim()
if (!f2fs_hw_support_discard(F2FS_SB(sb)))
return -EOPNOTSUPP;
So this should not happen that two partitions locates in one device have
inconsistent discard support status.
Thanks,
