checkpatch does not point out that VM_BUG_ON() and friends should be avoided, however, Linus notes: VM_BUG_ON() has the exact same semantics as BUG_ON. It is literally no different, the only difference is "we can make the code smaller because these are less important". [1] So let's warn on VM_BUG_ON() and other BUG variants as well. While at it, make it clearer that the kernel really shouldn't be crashed. As there are some subsystem BUG macros that actually don't end up crashing the kernel -- for example, KVM_BUG_ON() -- exclude these manually.

Linus notes [1] that the introduction of new code that uses VM_BUG_ON() is just as bad as BUG_ON(), because it will crash the kernel on distributions that enable CONFIG_DEBUG_VM (like Fedora): VM_BUG_ON() has the exact same semantics as BUG_ON. It is literally no different, the only difference is "we can make the code smaller because these are less important". [2] This resulted in a more generic discussion about usage of BUG() and friends. While there might be corner cases that still deserve a BUG_ON(), most BUG_ON() cases should simply use WARN_ON_ONCE() and implement a recovery path if reasonable: The only possible case where BUG_ON can validly be used is "I have some fundamental data corruption and cannot possibly return an error". [2] As a very good approximation is the general rule: "absolutely no new BUG_ON() calls _ever_" [2] ... not even if something really shouldn't ever happen and is merely for documenting that an invariant always has to hold. However, there are sill exceptions where BUG_ON() may be used: If you have a "this is major internal corruption, there's no way we can continue", then BUG_ON() is appropriate. [3] There is only one good BUG_ON(): Now, that said, there is one very valid sub-form of BUG_ON(): BUILD_BUG_ON() is absolutely 100% fine. [2] While WARN will also crash the machine with panic_on_warn set, that's exactly to be expected: So we have two very different cases: the "virtual machine with good logging where a dead machine is fine" - use 'panic_on_warn'. And the actual real hardware with real drivers, running real loads by users. [4] The basic idea is that warnings will similarly get reported by users and be found during testing. However, in contrast to a BUG(), there is a way to actually influence the expected behavior (e.g., panic_on_warn) and to eventually keep the machine alive to extract some debug info. Ingo notes that not all WARN_ON_ONCE cases need recovery. If we don't ever expect this code to trigger in any case, recovery code is not really helpful. I'd prefer to keep all these warnings 'simple' - i.e. no attempted recovery & control flow, unless we ever expect these to trigger. [5] There have been different rules floating around that were never properly documented. Let's try to clarify.

The top-level index.rst file is the entry point for the kernel's documentation, especially for readers of the HTML output. It is currently a mess containing everything we thought to throw in there. Firefox says it would require 26 pages of paper to print it. That is not a user-friendly introduction. This series aims to improve our documentation entry point with a focus on rewriting index.rst. The result is, IMO, simpler and more approachable. For anybody who wants to see the rendered results without building the docs, have a look at: https://static.lwn.net/kerneldoc/ This time around I've rendered the pages using the "Read The Docs" theme, since that's what everybody will get by default. That theme ignores the directives regarding the left column, so the results are not as good there. I have a series proposing a default-theme change in the works, but that's a separate topic. This is only a beginning; I think this kind of organizational effort has to be pushed down into the lower layers of the docs tree itself. But one has to start somewhere.

These files describe part of the core API, but have never been converted to RST due to ... let's say local oppposition. So, create a set of special-purpose wrappers to ..include these files into a separate page so that they can be a part of the htmldocs build. Then link them into the core-api manual and remove them from the "staging" dumping ground. Acked-by:
