From: David Daney <david.daney@xxxxxxxxxx> For v3: No code changes. Fix comment text in kernel.h to correctly reflect the name BUILD_BUG(). Updated patch chanegelogs with slightly better descriptions and some Acked-by: headers. Andrew, since you have version 2 in you tree currently, can you replace those patches with this version instead? Thanks, David Daney >From v2: As suggested by 'DM', call the macro BUILD_BUG() instead of BUILD_BUG_ON_USED(). Linus seemed satisfied with this, so if it still looks good, can we put it in some linux-next tree (Perhaps Andrew Morton's) to cook for a while? The second patch now covers linux/huge_mm.h too. >From v1: After some, perhaps justified, reluctance to merge dummy symbol definitions containing BUG() into header files, I propose these patches instead. We define a new compile time assertion BUILD_BUG_ON_USED() that can be used in places were we expect the compiler's dead code elimination to get rid of code. This happens mostly in code dealing with huge pages, but in other places as well. The first patch adds BUILD_BUG_ON_USED(), the second gets rid of one of the main abusers of BUG().
