The kernel since version v5.2-rc1 exports information about built-in modules in the modules.builtin.modinfo. Now, kmod can show complete information about the built-in modules as well as about external modules. Also kmod can understand aliases of built-in modules. Before: $ modinfo block-major-9-1 modinfo: ERROR: Module block-major-9-1 not found. After: $ modinfo block-major-9-1 name: md_mod filename: (builtin) alias: block-major-9-* alias: md description: MD RAID framework license: GPL parm: start_dirty_degraded:int parm: create_on_open:bool v2: * Don't use kmod_file() to parse modules.builtin.modinfo. Instead, parser reads the file into the buffer by chunks, which reduces the amount of memory.
