Summary The Linux kernel, based on version 4.18.0, heavily modified with backports
Repositories RT
Description This is the package which provides the Linux kernel-rt for MSVSphere. It is based on upstream Linux at version 4.18.0 and maintains kABI compatibility of a set of approved symbols, however it is heavily modified with backports and fixes pulled from newer upstream Linux kernel-rt releases. This means this is not a 4.18.0 kernel anymore: it includes several components which come from newer upstream linux versions, while maintaining a well tested and stable core. Some of the components/backports that may be pulled in are: changes like updates to the core kernel (eg.: scheduler, cgroups, memory management, security fixes and features), updates to block layer, supported filesystems, major driver updates for supported hardware in MSVSphere, enhancements for enterprise customers, etc.
