According to Russell King, adfs was written to not require the big kernel lock, and all inode updates are done under adfs_dir_lock. All other metadata in adfs is read-only and does not require locking. The use of the BKL is the result of various pushdowns from the VFS operations.

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.txt> 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.
