I saw you have the describe file with allyesconfig v5.12 kernel but wonder why missing this built_in.bc
What maybe the problem in generate the syzlang with this folder generated bytecode file

Hi, currently SyzDescribe only supports the Character and Block device drivers~(e.g., open(), ioctl()). For the net device driver~(e.g., socket(), sendmsg()), please wait for my next update. I guess I can make it this year.
