Description Yousaf Kaukab 2023-05-29 13:42:45 UTC 
This is a tracker bug for mainline commits that are prerequisites for the preempt-rt tree. For commits that are safe, these will be merged to the SLE kernel to avoid significant deviations in functionality and behavior between SLE and SLERT in the future.
