The allocation in journal_init_common() (at least) _can_ recover and hence really shouldn't be using __GFP_NOFAIL. (Actually, nothing in the kernel should be using __GFP_NOFAIL. It is there as a marker which says "we really shouldn't be doing this but we don't know how to fix it"). So sometime it'd be good if you could review all the __GFP_NOFAILs in there and see if we can remove some, thanks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
