I haven't checked yet if 5.6-rt is also showing this size increase. At least, our SUSE spin off from v5.4-rt doesn't have this size increase with the same config. Would be interesting to see the size numbers for v5.6-rt? Hmm, I'll just start the compiler. It's all scripted anyway :) Anyway, the config is: make defconfig and # # Networking # CONFIG_PACKET=y CONFIG_UNIX=y CONFIG_INET=y CONFIG_IP_PNP=y CONFIG_IP_PNP_DHCP=y # NFS CONFIG_NETWORK_FILESYSTEMS=y CONFIG_NFS_FS=y CONFIG_NFS_V3=y CONFIG_NFS_V4=y CONFIG_NFS_V4_1=y CONFIG_NFS_V4_2=y CONFIG_ROOT_NFS=y # # Debugging # CONFIG_DEBUG_INFO=y CONFIG_PRINTK_TIME=y CONFIG_DEBUG_KERNEL=y CONFIG_EARLY_PRINTK=y CONFIG_MESSAGE_LOGLEVEL_DEFAULT=7 # Embedded config to kernel. /proc/config.gz CONFIG_IKCONFIG=y CONFIG_IKCONFIG_PROC=y CONFIG_KEXEC=y # Default settings # # CONFIG_DEBUG_WW_MUTEX_SLOWPATH is not set # CONFIG_DEBUG_LOCK_ALLOC is not set # CONFIG_PROVE_LOCKING is not set # CONFIG_LOCKDEP is not set CONFIG_DEBUG_ATOMIC_SLEEP=y # CONFIG_CPU_FREQ is not set # CONFIG_CPU_IDLE is not set # CONFIG_NO_HZ is not set CONFIG_HZ_PERIODIC=y CONFIG_HZ_250=y CONFIG_HZ=250 # CONFIG_SUSPEND is not set # CONFIG_HIBERNATION is not set # CONFIG_PM is not set # cyclicdeadline dependency CONFIG_SCHED_DEBUG=y CONFIG_RCU_EXPERT=y CONFIG_RCU_NOCB_CPU=y # tracing CONFIG_EMBEDDED=y CONFIG_EXPERT=y CONFIG_FTRACE=y CONFIG_FUNCTION_TRACER=y CONFIG_SCHED_TRACER=y CONFIG_PREEMPT_RT=y
