*	adfs: remove the big kernel lock	Arnd Bergmann	2011-03-02	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \| \|	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.	Arnd Bergmann	2010-10-21	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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>
