With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,
|
|
OpenBSD and NeXTstep) use a file system called UFS. Some System V
|
|
Unixes can create and mount hard disk partitions and diskettes using
|
|
this file system as well. Saying Y here will allow you to read from
|
|
these partitions; if you also want to write to them, say Y to the
|
|
experimental "UFS file system write support", below. Please read the
|
|
file <file:Documentation/filesystems/ufs.txt> for more information.
|
|
|
|
The recently released UFS2 variant (used in FreeBSD 5.x) is
|
|
READ-ONLY supported.
|
|
|
|
Note that this option is generally not needed for floppies, since a
|
|
good portable way to transport files and directories between unixes
|
|
(and even other operating systems) is given by the tar program ("man
|
|
tar" or preferably "info tar").
|
|
|
|
When accessing NeXTstep files, you may need to convert them from the
|
|
NeXT character set to the Latin1 character set; use the program
|
|
recode ("info recode") for this purpose.
|
|
|
|
To compile the UFS file system support as a module, choose M here: the
|
|
module will be called ufs.
|
|
|
|
If you haven't heard about all of this before, it's safe to say N.

Say Y here if you want to try writing to UFS partitions. This is

If you are experiencing any problems with the UFS filesystem, say
|
|
Y here. This will result in _many_ additional debugging messages to be
|
|
written to the system log.
