      fbdefio: add set_page_dirty handler to deferred IO FB · d847471d
      Ian Campbell authored
      Fixes kernel BUG at lib/radix-tree.c:473.
      
      Previously the handler was incidentally provided by tmpfs but this was
      removed with:
      
        commit 14fcc23f

        Date:   Mon Jul 28 15:46:19 2008 -0700
      
          tmpfs: fix kernel BUG in shmem_delete_inode
      
      relying on this behaviour was incorrect in any case and the BUG also
      appeared when the device node was on an ext3 filesystem.
      
      v2: override a_ops at open() time rather than mmap() time to minimise
      races per AKPM's concerns.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau authored
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).
