To use this program type, the kernel must be compiled with CONFIG_BPF_IO_FILTER. Please add information in this paragraph about why one should or should not install a BPF I/O filter. What are the use cases for BPF I/O filters? I think the following information from the Kconfig file is useful: "Enables instrumentation of the hooks in block subsystem with eBPF programs for observing and filtering io." Thanks, Bart.
