Fixes (reboot,bpfloader-failed ~28s into boot) on Android 15. The hash map flag mask in the compiled kernel rejected BPF_F_RDONLY_PROG, which broke tether_dev_map (DEVMAP_HASH compat) and made netbpfload report a critical failure. Fixed by patching the mask constant in htab_map_alloc() in the kernel image (2-byte change, header SHA1 updated). Extras Compiled With Lastest Clang 21 Added Some BTF Things For Make Some ROMs Boot - PerfTune-N930X-runtime.zip (flash in TWRP): installs perf_tune.rc into /system/etc/init (runs after boot_completed). * I/O scheduler: cfq -> noop on sda..sdf, iostats and add_random off * workqueue power_efficient on * printk loglevel 3 * Exynos CPU hotplug governor off, all 8 cores kept online (uses a bit more battery) Notes - Tested on: SM-N930F (update this line with your result).
