2.4.0b1	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk Cloud (CCE), Checkmk MSP (CME)
2.3.0	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk Cloud (CCE), Checkmk MSP (CME)
2.2.0p26	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk Cloud (CCE), Checkmk MSP (CME)

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.
