  • 3c18d4de8   Expand CONFIG_DEBUG_LIST to several other list operations ... Browse Code »

    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..

  • e3f76e338   list debugging: warn when deleting a deleted entry ... Browse Code »

    Use the magic LIST_POISON* values to detect an incorrect use of list_del
    on a deleted entry. This DEBUG_LIST specific warning is easier to
    understand than the generic Oops message caused by LIST_POISON
    dereference.

  • 924d9addb   list debugging: use WARN() instead of BUG() ... Browse Code »

    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

  • e0ce0da9f   lists: remove a redundant conditional definition of list_add() ... Browse Code »

    Remove the conditional surrounding the definition of list_add() from list.h
    since, if you define CONFIG_DEBUG_LIST, the definition you will subsequently
    pick up from lib/list_debug.c will be absolutely identical, at which point you
    can remove that redundant definition from list_debug.c as well.

  • 8f63fdbbd   [PATCH] More list debugging context ... Browse Code »

    Print the other (hopefully) known good pointer when list_head debugging
    too, which may yield additional clues.

    Also fix for 80-columns to win akpm brownie points.

  • ab8e92efc   [PATCH] list_del-debug fix ... Browse Code »

    These two BUG_ON()s are redundant and undesired: we're checking for this
    condition further on in the function, only better.
