  • 4688a066e   adfs: remove the big kernel lock ... Browse Code »

    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.

  • 6de5bd128   BKL: introduce CONFIG_BKL. ... Browse Code »

    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.
