I didn't really look outside of do_mounts.c, but once doing that it becomes completely obvious. > int __init get_filesystem_list(char *buf, bool is_dev) As-is we don't even really need the is_dev argument, as the only callers wants block device file systems anyway. In fact it would much rather have a cursor based iteration so that we can skip the allocation, but that is probaby overengineering the problem.
