odroid-c2 linux 4.15 and eMMC [SOLVED - well work arround]

[summers]

Not quite sure how to test, but:
$this->bbcode_second_pass_code('', 'lsblk --discard
NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO
mmcblk0 0 0B 0B 0
`-mmcblk0p1 0 0B 0B 0
mmcblk0boot0 0 0B 0B 0
mmcblk0boot1 0 0B 0B 0
mmcblk1 0 0B 0B 0
`-mmcblk1p1 0 0B 0B 0
')

I know that mmcblk1 (the sd card) has ssd optimisations on it, its formatted btrfs, and that detects it:

$this->bbcode_second_pass_code('', '[ 9.049625] BTRFS: device label home devid 1 transid 35 /dev/mmcblk1p1
