Hi David, I found this this morning trying to boot up i.MX8MQ platform. It's totally unrelated though. Your commit: 2284cf59cbcec "hugetlbfs: Convert to fs_context" doesn't put a sentinel at the end of hugetlb_param_specs. Then, the your commit: f512b838c1048 "vfs: Add configuration parser helpers" adds the fs_validate_description where you check for sentinel but since the hugetlb_param_specs doesn't have it it freezes inside the following printf: + /* Check that the type is in range */ + if (t == __fs_param_wasnt_defined || + t >= nr__fs_parameter_type) { + pr_err("VALIDATE %s: PARAM[%s] Bad type %u\n", + name, param->name, t); + good = false; + } else if (t == fs_param_is_enum) { + enums = true; + } IMHO, what happens here is the missing sentinel allows your checking here to go out of bounds and then the param->name is whatever garbage happens to be at the end of that array and that makes the printf to freeze. This isn't something I looked at really close, so I might be wrong. I wasn't able to find the mail with the patch to reply to that so I had to write this as a separate mail.
