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.

The Acorn Disc Filing System is the standard file system of the
|
|
RiscOS operating system which runs on Acorn's ARM-based Risc PC
|
|
systems and the Acorn Archimedes range of machines. If you say Y
|
|
here, Linux will be able to read from ADFS partitions on hard drives
|
|
and from ADFS-formatted floppy discs. If you also want to be able to
|
|
write to those devices, say Y to "ADFS write support" below.
|
|
|
|
The ADFS partition should be the first partition (i.e.,
|
|
/dev/[hs]d?1) on each of your drives. Please read the file
|
|
<file:Documentation/filesystems/adfs.rst> for further details.

To compile this code as a module, choose M here: the module will be
|
|
called adfs.

If unsure, say N.

If you say Y here, you will be able to write to ADFS partitions on
|
|
hard drives and ADFS-formatted floppy disks. This is experimental
|
|
codes, so if you're unsure, say N.
