2022-03-23Documentation/sparse: add hints about __CHECKER__Bjorn Helgaas1-0/+2
Several attributes depend on __CHECKER__, but previously there was no clue in the tree about when __CHECKER__ might be defined. Add hints at the most common places (__kernel, __user, __iomem, __bitwise) and in the sparse documentation.

2020-07-05doc: add link to sparse's home page/internal docsLuc Van Oostenryck1-0/+2
Sparse's home page used to be a wiki (sparse.wiki.kernel.org) but this wiki only contained a short intro and the release notes. But nowadays, sparse's main page is sparse.docs.kernel.org, which contains all what was in the wiki but also other documentation, mainly oriented about sparse's internals. So, add a link to this in the kernel documentation.

2020-06-26doc: update URL for sparse's tarballsLuc Van Oostenryck1-2/+2
The URL given to get sparse's tarballs is sparse.wiki.kernel.org but the wiki will is deprecated in favor of sparse.docs.kernel.org. So, update this URL to the one where the tarballs can directly be found.

This fell into disrepair a while ago, and the majority of hits to the snapshots were from bots, so it's more trouble to keep running than it's worth. Signed-off-by: Dave Jones <davej@codemonkey.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2017-06-08rcu: Remove SPARSE_RCU_POINTER Kconfig optionPaul E. McKenney1-6/+0
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>
2017-02-15Improve sparse documentationMatthew Wilcox1-0/+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>
2016-12-16Documentation/sparse: drop __CHECK_ENDIAN__Michael S. Tsirkin1-6/+1
It's no longer used. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2016-12-16Documentation/sparse: drop __bitwise__Michael S. Tsirkin1-7/+0
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>
