[LTP] [PATCH] inode01: increase dev_min_size to fit the peak usage in parallel scenario

[Avinesh Kumar via ltp]

From: Avinesh Kumar <avinesh.kumar@suse.com>

The parallel scenario keeps every worker's tree on the device at the same
time. On exfat each object costs a full cluster and mkfs.exfat defaults to
32K cluster size for a volume above 256M, causing ENOSPC on a 300M device.
Increase the dev_min_size to 512M.

commit message and dev_min_size in the patch dont match the value.
The commit message needs to be changed before merge.
