    Unnecessary casts of void * clutter the code.

    These are the remainder casts after several specific
    patches to remove netdev_priv and dev_priv.

    Done via coccinelle script (and a little editing):

    $ cat cast_void_pointer.cocci

    type T;
    T *pt;
    void *pv;

  • 60d9f461a   appletalk: remove the BKL ... Browse Code »

    This changes appletalk to use lock_sock instead of
    lock_kernel for serialization. I tried to make sure
    that we don't hold the socket lock during sleeping
    functions, but I did not try to prove whether the
    locks are necessary in the first place.

    Compile-tested only.

  • 6de5bd128   BKL: introduce CONFIG_BKL. ... Browse Code »

    With all the patches we have queued in the BKL removal tree, only a
    few dozen modules are left that actually rely on the BKL, and even
    there are lots of low-hanging fruit. We need to decide what to do
    about them, this patch illustrates one of the options:

    Every user of the BKL is marked as 'depends on BKL' in Kconfig,
    and the CONFIG_BKL becomes a user-visible option. If it gets
    disabled, no BKL using module can be built any more and the BKL
    code itself is compiled out.

    The one exception is file locking, which is practically always
    enabled and does a 'select BKL' instead. This effectively forces
    CONFIG_BKL to be enabled until we have solved the fs/lockd
    mess and can apply the patch that removes the BKL from fs/locks.c.

  • a4b770972   drivers/net: Remove unnecessary returns from void function()s ... Browse Code »

    This patch removes from drivers/net/ all the unnecessary
    return; statements that precede the last closing brace of
    void functions.

    It does not remove the returns that are immediately
    preceded by a label as gcc doesn't like that.

    It also does not remove null void functions with return.

    Done via:
    $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
    xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

    with some cleanups by hand.

    Compile tested x86 allmodconfig only.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 93f154b59   net: release dst entry in dev_hard_start_xmit() ... Browse Code »

    One point of contention in high network loads is the dst_release() performed
    when a transmited skb is freed. This is because NIC tx completion calls
    dev_kree_skb() long after original call to dev_queue_xmit(skb).

    CPU cache is cold and the atomic op in dst_release() stalls. On SMP, this is
    quite visible if one CPU is 100% handling softirqs for a network device,
    since dst_clone() is done by other cpus, involving cache line ping pongs.

    It seems right place to release dst is in dev_hard_start_xmit(), for most
    devices but ones that are virtual, and some exceptions.

    David Miller suggested to define a new device flag, set in alloc_netdev_mq()
    (so that most devices set it at init time), and carefuly unset in devices
    which dont want a NULL skb->dst in their ndo_start_xmit().

    List of devices that must clear this flag is :

    - loopback device, because it calls netif_rx() and quoting Patrick :
    "ip_route_input() doesn't accept loopback addresses, so loopback packets
    already need to have a dst_entry attached."
    - appletalk/ipddp.c : needs skb->dst in its xmit function

    - And all devices that call again dev_queue_xmit() from their xmit function
    (as some classifiers need skb->dst) : bonding, vlan, macvlan, eql, ifb, hdlc_fr

  • 454d7c9b1   netdevice: safe convert to netdev_priv() #part-1 ... Browse Code »

    We have some reasons to kill netdev->priv:
    1. netdev->priv is equal to netdev_priv().
    2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
    netdev_priv() is more flexible than netdev->priv.
    But we cann't kill netdev->priv, because so many drivers reference to it
    directly.

    This patch is a safe convert for netdev->priv to netdev_priv(netdev).
    Since all of the netdev->priv is only for read.
    But it is too big to be sent in one mail.
    I split it to 4 parts and make every part smaller than 100,000 bytes,
    which is max size allowed by vger.
