[PATCH] Debug variants of linked list macros Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

lib: reduce the use of module.h wherever possible For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

bug.h: add include of it to various implicit C users With bug.h currently living right in linux/kernel.h there are files that use BUG_ON and friends but are not including the header explicitly. Fix them up so we can remove the presence in kernel.h file. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

lib: fix implicit users of kernel.h for TAINT_WARN A pending header cleanup will cause this to show up as: lib/average.c:38: error: 'TAINT_WARN' undeclared (first use in this function) lib/list_debug.c:24: error: 'TAINT_WARN' undeclared (first use in this function) and TAINT_WARN comes from include/linux/kernel.h file.

rcu: List-debug variants of rcu list routines. * Make __list_add_rcu check the next->prev and prev->next pointers just like __list_add does. * Make list_del_rcu use __list_del_entry, which does the same checking at deletion time. Has been running for a week here without anything being tripped up, but it seems worth adding for completeness just in case something ever does corrupt those lists.

list debugging: use WARN() instead of BUG() Arjan noted that the list_head debugging is BUG'ing when it detects corruption. By causing the box to panic immediately, we're possibly losing some bug reports. Changing this to a WARN() should mean we at the least start seeing reports collected at kerneloops.org Signed-off-by: Dave Jones <davej@redhat.com> Cc: Matthew Wilcox <matthew@wil.cx> Cc: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Expand CONFIG_DEBUG_LIST to several other list operations When list debugging is enabled, we aim to readably show list corruption errors, and the basic list_add/list_del operations end up having extra debugging code in them to do some basic validation of the list entries. However, "list_del_init()" and "list_move[_tail]()" ended up avoiding the debug code due to how they were written. This fixes that. So the _next_ time we have list_move() problems with stale list entries, we'll hopefully have an easier time finding them.. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
