      adfs: remove the big kernel lock · 4688a066
      Arnd Bergmann authored
      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.

      BKL: introduce CONFIG_BKL. · 6de5bd12
      Arnd Bergmann authored
      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.
