Christoph Hellwig 925c86a19b fs: add CONFIG_BUFFER_HEAD
Add a new config option that controls building the buffer_head code, and
select it from all file systems and stacking drivers that need it.

For the block device nodes and alternative iomap based buffered I/O path
is provided when buffer_head support is not enabled, and iomap needs a
a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call
into the buffer_head code when it doesn't exist.

Otherwise this is just Kconfig and ifdef changes.

Minix is a simple operating system used in many classes about OS's.
The minix file system (method to organize files on a hard disk
partition or a floppy disk) was the original file system for Linux,
but has been superseded by the second extended file system ext2fs.
You don't want to use the minix file system on your hard disk
because of certain built-in restrictions, but it is sometimes found
on older Linux floppy disks. This option will enlarge your kernel
by about 28 KB. If unsure, say N.
To compile this file system support as a module, choose M here: the
module will be called minix. Note that the file system of your root
partition (the one containing the directory /) cannot be compiled as
a module.
