Thanks a lot for the attack, but of course I have. It's the same stupid idea of throwing almost generic code into filesystems that you previous attempt did. It's completely generic code for checking what pages are in-memory (plus constaints) and then force read-ahead on them again. The only filesystems specific bit is which address_space to select. The whole apporach is also useful to extN / xfs / etc if you allow it on any address_space. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
