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but has been superseded by the second extended file system ext2fs.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.
