QA output created by 096

# su too big but must be a multiple of fs block size too
--- mkfs=-l version=2,su=262656 ---
log stripe unit (262656) must be a multiple of the block size (4096)


# test log stripe greater than LR size
--- mkfs=-l version=2,su=266240 ---
log stripe unit (266240 bytes) is too large (maximum is 256KiB)
log stripe unit adjusted to 32KiB
