      atm: Convert compare_ether_addr to ether_addr_equal · 150238eb
      Joe Perches authored
      Use the new bool function ether_addr_equal to add
      some clarity and reduce the likelihood for misuse
      of compare_ether_addr for sorting.
      Done via cocci script:
      $ cat compare_ether_addr.cocci
      expression a,b;
      -	!compare_ether_addr(a, b)
      +	ether_addr_equal(a, b)
      expression a,b;
      -	compare_ether_addr(a, b)
      +	!ether_addr_equal(a, b)
      expression a,b;
      -	!ether_addr_equal(a, b) == 0
      +	ether_addr_equal(a, b)
      expression a,b;
      -	!ether_addr_equal(a, b) != 0
      +	!ether_addr_equal(a, b)
      expression a,b;
      -	ether_addr_equal(a, b) == 0
      +	!ether_addr_equal(a, b)
      expression a,b;
      -	ether_addr_equal(a, b) != 0
      +	ether_addr_equal(a, b)
      expression a,b;
      -	!!ether_addr_equal(a, b)
      +	ether_addr_equal(a, b)

      workqueue: convert cancel_rearming_delayed_work[queue]() users to cancel_delayed_work_sync() · afe2c511

      cancel_rearming_delayed_work[queue]() has been superceded by
      cancel_delayed_work_sync() quite some time ago.  Convert all the
      in-kernel users.  The conversions are completely equivalent and

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit 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.
      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
      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
      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
      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.

      netdevice: safe convert to netdev_priv() #part-4 · 524ad0a7
      Wang Chen authored
      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
      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.

      [NET]: Undo code bloat in hot paths due to print_mac(). · 21f644f3
      David S. Miller authored
      If print_mac() is used inside of a pr_debug() the compiler
      can't see that the call is redundant so still performs it
      even of pr_debug() ends up being a nop.
      So don't use print_mac() in such cases in hot code paths,
      use MAC_FMT et al. instead.
      As noted by Joe Perches, pr_debug() could be modified to
      handle this better, but that is a change to an interface
      used by the entire kernel and thus needs to be validated
      carefully.  This here is thus the less risky fix for
