    Implement device resource management, in short, devres. A device
    driver can allocate arbirary size of devres data which is associated
    with a release function. On driver detach, release function is
    invoked on the devres data, then, devres data is freed.

    devreses are typed by associated release functions. Some devreses are
    better represented by single instance of the type while others need
    multiple instances sharing the same release function. Both usages are
    supported.

    devreses can be grouped using devres group such that a device driver
    can easily release acquired resources halfway through initialization
    or selectively release resources (e.g. resources for port 1 out of 4
    ports).

    This patch adds devres core including documentation and the following
    managed interfaces.

    * alloc/free : devm_kzalloc(), devm_kzfree()
    * IO region : devm_request_region(), devm_release_region()
    * IRQ : devm_request_irq(), devm_free_irq()
    * DMA : dmam_alloc_coherent(), dmam_free_coherent(),
    dmam_declare_coherent_memory(), dmam_pool_create(),
    dmam_pool_destroy()
    * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed()
    * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(),
    devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(),
    pcim_iomap(), pcim_iounmap()

  • dd0fc66fb   [PATCH] gfp flags annotations - part 1 ... Browse Code »

    - added typedef unsigned int __nocast gfp_t;

    - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
    the same warnings as far as sparse is concerned, doesn't change
    generated code (from gcc point of view we replaced unsigned int with
    typedef) and documents what's going on far better.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
