The original shell script works, but: 1) it is too slow; 2) it is hard to exclude rejex patterns Convert it to perl. Here, the new version is able to check the entire tree in less than a second (after cached): real 0m0,284s user 0m0,668s sys 0m0,778s The old version takes more than a minute to complete (also after cached): real 1m17,905s user 0m25,583s sys 0m55,334s It also produce less false-positives (if any). The new script also contains an auto-fix mode. Usually, file references get lost when they're moved to some other place and/or renamed to .rst. Add an experimental mode to auto-fix those.

The removal of this file appears to have been premature; it's not a feature enabled by Kconfig, but it's a arch-level feature regardless. Put it back for now until some happy future time when we decide how we really want to document such features. This reverts commit 2bef69a3. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

The document describes NUMA memory policy and as it is a part of the Linux documentation it's obvious that this is Linux memory policy. Besides, "Linux memory policy" may refer to other policies, e.g. memory hotplug policy, and using term NUMA makes the documentation less ambiguous.

Uses '!RWSEM_GENERIC_SPINLOCK' in place of 'Optimized asm/rwsem.h' as Kconfig for 'rwsem-optimized': the new Kconfig expresses this feature equivalently, while also enabling the script 'features-refresh.sh' to operate on the corresponding arch support status file. Also refreshes the status matrix by using the script 'features-refresh.sh'.

Provides the script: Documentation/features/scripts/features-refresh.sh which operates on the arch-support.txt files and refreshes them in place. This way [1], "[...] we soft- decouple the refreshing of the entries from the introduction of the features, while still making it all easy to keep sync and to extend."
