  • 8a79790bf   afs: Migrate vlocation fields to 64-bit ... Browse Code »

    get_seconds() returns real wall-clock seconds. On 32-bit systems
    this value will overflow in year 2038 and beyond. This patch changes
    afs's vlocation record to use ktime_get_real_seconds() instead, for the
    fields time_of_death and update_at.

  • 8324f0bcf   rxrpc: Provide a way for AFS to ask for the peer address of a call ... Browse Code »

    Provide a function so that kernel users, such as AFS, can ask for the peer
    address of a call:

    void rxrpc_kernel_get_peer(struct rxrpc_call *call,
    struct sockaddr_rxrpc *_srx);

    In the future the kernel service won't get sk_buffs to look inside.
    Further, this allows us to hide any canonicalisation inside AF_RXRPC for
    when IPv6 support is added.

    Also propagate this through to afs_find_server() and issue a warning if we
    can't handle the address family yet.

  • 41f63c535   workqueue: use mod_delayed_work() instead of cancel + queue ... Browse Code »

    Convert delayed_work users doing cancel_delayed_work() followed by
    queue_delayed_work() to mod_delayed_work().

    Most conversions are straight-forward. Ones worth mentioning are,

    * drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
    use mod_delayed_work() and cancel loop in
    edac_mc_reset_delay_period() is dropped.

    * drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
    watchdog is active or not. @fan_watchdog_active and related code
    dropped.

    * drivers/power/charger-manager.c: Seemingly a lot of
    delayed_work_pending() abuse going on here.
    [delayed_]work_pending() are unsynchronized and racy when used like
    this. I converted one instance in fullbatt_handler(). Please
    conver the rest so that it invokes workqueue APIs for the intended
    target state rather than trying to game work item pending state
    transitions. e.g. if timer should be modified - call
    mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().

    * drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
    simplified. Note that round_jiffies() calls in this function are
    meaningless. round_jiffies() work on absolute jiffies not delta
    delay used by delayed_work.

    v2: Tomi pointed out that __cancel_delayed_work() users can't be
    safely converted to mod_delayed_work(). They could be calling it
    from irq context and if that happens while delayed_work_timer_fn()
    is running, it could deadlock. __cancel_delayed_work() users are
    dropped.

  • 0ad53eeef   afs: add afs_wq and use it instead of the system workqueue ... Browse Code »

    flush_scheduled_work() is going away. afs needs to make sure all the
    works it has queued have finished before being unloaded and there can
    be arbitrary number of pending works. Add afs_wq and use it as the
    flush domain instead of the system workqueue.

    Also, convert cancel_delayed_work() + flush_scheduled_work() to
    cancel_delayed_work_sync() in afs_mntpt_kill_timer().

    - proc.c: afs_vlocation_states[]
    - server.c: afs_server_timeout
    - vlocation.c: afs_vlocation_timeout
    - vlocation.c: afs_vlocation_update_timeout
    - #if 0 the following unused function:

  • 416351f28   AFS: AFS fixups ... Browse Code »

    Make some miscellaneous changes to the AFS filesystem:

    (1) Assert RCU barriers on module exit to make sure RCU has finished with
    callbacks in this module.

    (2) Correctly handle the AFS server returning a zero-length read.

    (3) Split out data zapping calls into one function (afs_zap_data).

    (4) Rename some afs_file_*() functions to afs_*() where they apply to
    non-regular files too.

    (5) Be consistent about the presentation of volume ID:vnode ID in debugging
    output.

    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!
