* rcu: Remove SPARSE_RCU_POINTER Kconfig optionPaul E. McKenney2017-06-091-6/+0Star
| | | | | | | | | | | The sparse-based checking for non-RCU accesses to RCU-protected pointers has been around for a very long time, and it is now the only type of sparse-based checking that is optional. This commit therefore makes it unconditional. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Fengguang Wu <fengguang.wu@intel.com>
* Improve sparse documentationMatthew Wilcox2017-02-151-0/+6
| | | | | | | | | Add documentation of -DCONFIG_SPARSE_RCU_POINTER. I started to add documentation of -D__CHECK_ENDIAN__ as well, but discovered I'm too late; that's now enabled by default. Signed-off-by: Matthew Wilcox <mawilcox@microsoft.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
* Documentation/sparse: drop __CHECK_ENDIAN__Michael S. Tsirkin2016-12-151-6/+1Star
| | | | | | It's no longer used. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* Documentation/sparse: drop __bitwise__Michael S. Tsirkin2016-12-151-7/+0Star
| | | | | | | We dropped __CHECK_ENDIAN__ so __bitwise__ is now an implementation detail. People should use __bitwise everywhere. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
