  • 01d553d0f   [PATCH] Chardev checking of overlapping ranges ... Browse Code »

    The code in __register_chrdev_region checks that if the driver wishing to
    register has the same major as an existing driver the new minor range is
    strictly less than the existing minor range. However, it does not also
    check that the new minor range is strictly greater than the existing minor
    range. That is, if driver X has registered with major=x and minor=0-3,
    __register_chrdev_region will allow driver Y to register with major=x and
    minor=1-4.

    Set the backing device info capabilities for /dev/mem and /dev/kmem to
    permit direct sharing under no-MMU conditions and full mapping capabilities
    under MMU conditions. Make the BDI used by these available to all directly
    mappable character devices.

    Also comment the capabilities for /dev/zero.

  • 68eef3b47   [PATCH] Simplify proc/devices and fix early termination regression ... Browse Code »

    Make baby-simple the code for /proc/devices. Based on the proven design
    for /proc/interrupts.

    This also fixes the early-termination regression 2.6.16 introduced, as
    demonstrated by:

    # dd if=/proc/devices bs=1
    Character devices:
    1 mem
    27+0 records in
    27+0 records out

    This should also work (but is untested) when /proc/devices >4096 bytes,
    which I believe is what the original 2.6.16 rewrite fixed.

  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

    Mark the f_ops members of inodes as const, as well as fix the
    ripple-through this causes by places that copy this f_ops and then "do
    stuff" with it.

    A Christoph suggested that the /proc/devices file be converted to use the
    seq_file interface. This patch does that.

    I've obxerved one or two installation that had sufficiently large sans that
    they overran the 4k limit on /proc/devices.

  • 7da6844cf   [PATCH] cdev: cdev_put oops ... Browse Code »

    While fixing an oops in the st driver in a dirty release path, I
    encountered an oops in cdev_put for cdevs allocated using cdev_alloc. If
    cdev_del is called when the cdev kobject still has an open user, when the
    last cdev_put is called, the cdev_put will call kobject_put, which will end
    up ultimately releasing the cdev in cdev_dynamic_release. Patch fixes the
    oops by preventing cdev_put from accessing freed memory.

  • 1d4d5b325   [PATCH] revert fs/char_dev.c CONFIG_BASE_FULL change ... Browse Code »

    This reverts a fs/char_dev.c patch that was merged into BK on March 3.

    The problem is that it breaks things ... __register_chrdev_region() has
    a block of code, commented "temporary" for over two years now, which
    fails rudely during PCMCIA initialization or other register_chrdev()
    calls, because it doesn't "degrade to linked list". This keeps whole
    subsystems from working.

    A real fix to that "temporary" code should be possible, using some better
    scheme to allocate major numbers, but it's not something I want to spend
    time on just now.

    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!
