As it seems to be rather unclear if/when to use BUG(), BUG_ON(), VM_BUG_ON(), WARN_ON_ONCE(), ... let's try to document the result of a recent discussion.
Details can be found in patch #1.
RFC -> v1: * "coding-style.rst: document BUG() and WARN() rules ("do not crash the kernel")" -> Rephrase/extend according to John -> Add some details regarding the use of panic() * powerpc/prom_init: drop PROM_BUG() -> Added * "checkpatch: warn on usage of VM_BUG_ON() and other BUG variants" -> Warn on more variants
