The default size of file cache is size of a sector, it may
not be good size for optimizing read/write speed in physical
device. So we can set the config according to speed test profile
to optimize access IO speed.

When ps cmd is invoked during the task exit process, the group information of the task may be deleted.
So need check the task flag before get the task group information.
1. Don't handle invalid or empty pte entries
num_partition_entries field in GPT typically means number of maximum entries
and not the number of used entries. Empty entries are indentified with
"0" partition type guid. Loop through all the entries
2. Fix the GPT partition size calculation
"ending_lba" is included in the partition, it is not the start of the next one.
Thus the correct size of the partition is end-start+1
