[2.3.0] Checkmk Werk 16554 created: df: Wrong handling of lower levels for free space

[//]: # (werk v2) # df: Wrong handling of lower levels for free space key | value ---------- | --- compatible | yes version | 2.3.0b7 date | 2024-04-19T12:35:12+00:00 level | 1 class | fix component | checks edition | cre This is a regression since Checkmk 2.2.0. When configuring the Service Monitoring Rule "Filesystems (used space and growth)", configured levels for free space were evaluated incorrectly. As a result, affected services erroneously showed up as *CRIT*. This happened because of a wrong rounding while evaluating the levels, and only affected small filesystems with a size below 1MB.
