    make messages produced by ext2 more unified. It should be
    easy to parse.

  • 70688e4dd   xip: support non-struct page backed memory ... Browse Code »

    Convert XIP to support non-struct page backed memory, using VM_MIXEDMAP for
    the user mappings.

    This requires the get_xip_page API to be changed to an address based one.
    Improve the API layering a little bit too, while we're here.

    This is required in order to support XIP filesystems on memory that isn't
    backed with struct page (but memory with struct page is still supported too).

  • 30afcb4bd   return pfn from direct_access, for XIP ... Browse Code »

    Alter the block device ->direct_access() API to work with the new
    get_xip_mem() API (that requires both kaddr and pfn are returned).

    Some architectures will not do the right thing in their virt_to_page() for use
    by XIP (to translate from the kernel virtual address returned by
    direct_access(), to a user mappable pfn in XIP's page fault handler.

    However, we can't switch it to just return the pfn and not the kaddr, because
    we have no good way to get a kva from a pfn, and XIP requires the kva for its
    read(2) and write(2) handlers. So we have to return both.

  • 0cfc11ed4   [PATCH] fix xip sparse file handling in ext2 ... Browse Code »

    Oliver Paukstadt from our test department is testing the xip patches in
    Linus' git-tree. He found a problem that shows when reading a file that
    contains sparse blocks (holes) on a -o xip mounted ext2 filesystem: the
    BUG_ON() in fs/ext2/xip.c:40 triggers where it should not. The problem was
    introduced by a cleanup in my previous patch, this patch fixes it.

  • afa597ba2   [PATCH] execute-in-place fixes ... Browse Code »

    This patch includes feedback from Andrew and Christoph. Thanks for
    taking time to review.

    Use of empty_zero_page was eliminated to fix compilation for architectures
    that don't have it.

    This patch removes setting pages up-to-date in ext2_get_xip_page and all
    bug checks to verify that the page is indeed up to date. Setting the page
    state on mapping to userland is bogus. None of the code patchs involved
    with these pages in mm cares about the page state.

    still on my ToDo list: identify a place outside second extended where
    __inode_direct_access should reside
