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.
Vitaly Kuznetsov (3): lib/string_helpers: change blk_size to u32 for string_get_size() interface lib/string_helpers.c: don't lose precision in string_get_size() lib/test-string_helpers.c: add string_get_size() tests
