[LTP] [PATCH] zram: extend the zram3 disksize to 40MB

[Li Wang]

It failed to format btrfs on /dev/zram3 device since the
disk size is too small (btrfs-progs is v4.4.1).

The error msg we catched:

zram01 3 TINFO : make ext3 filesystem on /dev/zram0
zram01 3 TINFO : make ext4 filesystem on /dev/zram1
zram01 3 TINFO : make xfs filesystem on /dev/zram2
zram01 3 TINFO : make btrfs filesystem on /dev/zram3
'/dev/zram3' is too small to make a usable filesystem
Minimum size for each btrfs device is 41943040.
btrfs-progs v4.4.1
See http://btrfs.wiki.kernel.org for more information.
zram01 3 TFAIL : failed to make btrfs on /dev/zram3
zram01 4 TINFO : zram cleanup
