unavailable (BZ#2228163)\n* oops on cifs_mount due to null tcon (BZ#2229128)\n* iptables argument \"--suppl-groups\" in extension \"owner\" does not work in AlmaLinux8 (BZ#2229715)\n* Hyper-V AlmaLinux 8: incomplete fc_transport implementation in storvsc causes null dereference in fc_timed_out() (BZ#2230743)\n* Withdrawal: GFS2: could not freeze filesystem: -16 (BZ#2231825)\n* AlmaLinux 8 Hyper-V: Excessive hv_storvsc driver logging with srb_status  SRB_STATUS_INTERNAL_ERROR  (0x30) (BZ#2231988)\n* AlmaLinux-8: crypto: rng - Fix lock imbalance in crypto_del_rng (BZ#2232215)\n* Intel 8.9 iavf: Driver Update (BZ#2232399)\n* Hyper-V AlmaLinux-8 hv_storvsc driver logging excessive storvsc_log events for storvsc_on_io_completion() function (BZ#2233227)\n\nEnhancement(s):\n\n* Intel 8.9 FEAT, EMR perf: Add EMR CPU PMU support (BZ#2230152)\n* Intel 8.9 FEAT, SPR EMR power: Add uncore frequency control driver (BZ#2230158)\n* Intel 8.9 FEAT EMR perf: RAPL PMU support on EMR
