  • This replaces all instances of lock_kernel in the
    IPX code with lock_sock. As far as I can tell, this
    is safe to do, because there is no global state
    that needs to be locked in IPX, and the code does
    not recursively take the lock or sleep indefinitely
    while holding it.

    Compile-tested only.

  • 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.
