This series of patches splits BUILD_BUG related macros out of "include/linux/bug.h" into new file "include/linux/build_bug.h" (patch 5), and changes the pointer type checking in the `container_of()` macro to deal with pointers of array type better (patch 6). Patches 1 to 4 are prerequisites. Patches 2, 3, 4, and 5 have been inserted since the previous version of this patch series. Patch 6 here corresponds to v3 and v4's patch 2. Patch 1 was a prerequisite in v3 of this series to avoid a lot of warnings when <linux/bug.h> was included by <linux/kernel.h>. That is no longer relevant for v5 of the series, but I left it in because it was acked by a Arnd Bergmann and Michal Nazarewicz. Patches 2, 3, and 4 are some checkpatch clean-ups on "include/linux/bug.h" before splitting out the BUILD_BUG stuff in patch 5. Patch 5 splits the BUILD_BUG related macros out of "include/linux/bug.h" into new file "include/linux/build_bug.h" because including <linux/bug.h> in "include/linux/kernel.h" would result in build failures due to circular dependencies. Patch 6 changes the pointer type checking by `container_of()` to avoid some incompatible pointer warnings when the dereferenced pointer has array type. 1) asm-generic/bug.h: declare struct pt_regs; before function prototype 2) linux/bug.h: correct formatting of block comment 3) linux/bug.h: correct "(foo*)" should be "(foo *)" 4) linux/bug.h: correct "space required before that '-'" 5) bug: split BUILD_BUG stuff out into <linux/build_bug.h> 6) kernel.h: handle pointers to arrays better in container_of() This patch (of 6): The declaration of `__warn()` has `struct pt_regs *regs` as one of its parameters. This can result in compiler warnings if `struct regs` is not already declared. Add an empty declaration of `struct pt_regs` to avoid the warnings.
