Abhishek Arpure 4fec8e9e9a Integer overflow observed while formatting volume ...

While calculating volume size, get_block_device_size() returns
u64 value but the returned value is assigned in ssize_t variable.
This may cause integer overflow if the volume size is beyond
ssize_t limit.

Use int64_t instead of ssize_t in get_file_size() and explicitly check
for overflow to fix the issue.
