Linus Torvalds dda5df9823 Miscellaneous MMCID fixes to address bugs and ... performance regressions in the recent rewrite of the SCHED_MM_CID management code: - Fix livelock triggered by BPF CI testing - Fix hard lockup on weakly ordered systems - Simplify the dropping of CIDs in the exit path by removing an unintended transition phase. - Fix performance/scalability regression on a thread-pool benchmark by optimizing transitional CIDs when scheduling out.
