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.

This file system is often called HFS+ and was introduced with
|
|
MacOS 8. It includes all Mac specific filesystem data such as
|
|
data forks and creator codes, but it also has several UNIX
|

style features such as file ownership and permissions.
