      net: Explicitly initialize u64_stats_sync structures for lockdep · 827da44c
      John Stultz authored
      
      
      In order to enable lockdep on seqcount/seqlock structures, we
      must explicitly initialize any locks.
      
      The u64_stats_sync structure, uses a seqcount, and thus we need
      to introduce a u64_stats_init() function and use it to initialize
      the structure.
      
      This unfortunately adds a lot of fairly trivial initialization code
      to a number of drivers. But the benefit of ensuring correctness makes
      this worth while.
      
      Because these changes are required for lockdep to be enabled, and the
      changes are quite trivial, I've not yet split this patch out into 30-some
      separate patches, as I figured it would be better to get the various
      maintainers thoughts on how to best merge this change along with
      the seqcount lockdep enablement.
      
      Feedback would be appreciated!

      drivers/net: don't use flush_scheduled_work() · 23f333a2
      Tejun Heo authored
      
      
      flush_scheduled_work() is on its way out.  This patch contains simple
      conversions to replace flush_scheduled_work() usage with direct
      cancels and flushes.
      
      Directly cancel the used works on driver detach and flush them in
      other cases.
      
      The conversions are mostly straight forward and the only dangers are,
      
      * Forgetting to cancel/flush one or more used works.
      
      * Cancelling when a work should be flushed (ie. the work must be
        executed once scheduled whether the driver is detaching or not).
      
      I've gone over the changes multiple times but it would be much
      appreciated if you can review with the above points in mind.

      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.
      
        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.

      8139too: make PCI device ids constant · d160439e
      Márton Németh authored
      The id_table field of the struct pci_driver is constant in <linux/pci.h>
      so it is worth to make pci_device_id also constant.
