Arnd Bergmann 4688a066ec adfs: remove the big kernel lock
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.

config ADFS_FS
tristate "ADFS file system support (EXPERIMENTAL)"
depends on BLOCK && EXPERIMENTAL
help
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.

help
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.
