| Name| Description
| xref:BloombergLP/bslmt/FastPostSemaphoreImplWorkaroundUtil/removePostAlwaysSignalsMitigation.adoc[`removePostAlwaysSignalsMitigation`] 
| Remove the mitigation of `post` always signalling the condition variable. Note this mitigation was introduced as a work around for a lost signal bug in the underlying implementation of condition variable (e.g., https://sourceware.org/bugzilla/show_bug.cgi?id=25847). The availability of the pthread correction is tracked in DRQS 172614796, and the reversion of this workaround in DRQS 174079882.
| xref:BloombergLP/bslmt/FastPostSemaphoreImplWorkaroundUtil/usePostAlwaysSignalsMitigation.adoc[`usePostAlwaysSignalsMitigation`] 
| Return `true` if the mitigation of `post` always signalling the condition variable should be used, and `false` otherwise.
