Linux Kernel 3.11: With it comes a kernel-level API change related to VFS. Specifically, struct file_operations no longer contains the function pointer readdir and vfs_readdir() which was defined in fs/readdir.c is now gone. They are both superseded by iterate and iterate_dir() respectively. Linux Kernel 3.10: mnet/vmblock patch for Kernel 3.10 …
