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>

Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
|
|
never became an official part of the NFS version 3 protocol.
|
|
This protocol extension allows applications on NFS clients to
|
|
manipulate POSIX Access Control Lists on files residing on NFS
|
|
servers. NFS servers enforce POSIX ACLs on local files whether
|
|
this protocol is available or not.

This option enables support in your system's NFS server for the
|

NFSv3 ACL protocol extension allowing NFS clients to manipulate
|

POSIX ACLs on files exported by your system's NFS server. NFS
|
|
clients which support the Solaris NFSv3 ACL protocol can then
|
|
access and modify ACLs on your NFS server.
|
|

To store ACLs on your NFS server, you also need to enable ACL-
|

related CONFIG options for your local file systems of choice.
