CONFIG_ARCH_32BIT_OFF_T (not configurable)

configname: CONFIG_ARCH_32BIT_OFF_T

Linux Kernel Configuration
└─>General architecture-dependent options
└─>ARCH_32BIT_OFF_T
In linux kernel since version 5.1 (release Date: 2019-05-05)  
All new 32-bit architectures should have 64-bit off_t type on
userspace side which corresponds to the loff_t kernel type. This
is the requirement for modern ABIs. Some existing architectures
still support 32-bit off_t. This option is enabled for all such
architectures explicitly.
