  • 608e8e66a   mm: add a gfp-translate script to help understand page allocation failure reports ... Browse Code ยป

    The page allocation failure messages include a line that looks like

    page allocation failure. order:1, mode:0x4020

    The mode is easy to translate but irritating for the lazy and a bit error
    prone. This patch adds a very simple helper script gfp-translate for the
    mode: portion of the page allocation failure messages. An example usage
    looks like

    mel@machina:~/linux-2.6 $ scripts/gfp-translate 0x4020
    Source: /home/mel/linux-2.6
    Parsing: 0x4020
    #define __GFP_HIGH (0x20) /* Should access emergency pools? */
    #define __GFP_COMP (0x4000) /* Add compound page metadata */

    The script is not a work of art but it has come in handy for me a few
    times so I thought I would share.
