Linux always lies about your storage size when it has 4k sectors and its size
is big enough. E.g. a device with 8192 4k sectors will be reported as
"32.7 MB/32 MiB" while "33.5 MB/32 MiB" is expected. This series is supposed
to fix the issue by fixing calculation precision in string_get_size() for all
possible inputs.
PATCH 1/3 is a preparatory change, PATCH 2/3 re-factors string_get_size() fixing
the issue, PATCH 3/3 introduces tests for string_get_size().
PATCH 3/3 was previously sent as part of "lib/string_helpers.c: fix infinite
loop in string_get_size()" series but afaics wasn't merged. In this submission
I add additional tests to it.
