      [PATCH] export generic_drop_inode() to modules · cb2c0233
      Mark Fasheh authored
      OCFS2 wants to mark an inode which has been orphaned by another node so
      that during final iput it takes the correct path through the VFS and can
      pass through the OCFS2 delete_inode callback.  Since i_nlink can get out of
      date with other nodes, the best way I see to accomplish this is by clearing
      i_nlink on those inodes at drop_inode time.  Other than this small amount
      of work, nothing different needs to happen, so I think it would be cleanest
      to be able to just call generic_drop_inode at the end of the OCFS2
      drop_inode callback.

      [PATCH] Update cfq io scheduler to time sliced design · 22e2c507
      Jens Axboe authored
      This updates the CFQ io scheduler to the new time sliced design (cfq
      v3).  It provides full process fairness, while giving excellent
      aggregate system throughput even for many competing processes.  It
      supports io priorities, either inherited from the cpu nice value or set
      directly with the ioprio_get/set syscalls.  The latter closely mimic
      This import is based on my latest from -mm.

      [PATCH] Remove f_error field from struct file · 45778ca8
      Christoph Lameter authored
      The following patch removes the f_error field and all checks of f_error.
      Trond said:
        f_error was introduced for NFS, and made sense when we were guaranteed
        always to have a file pointer around when write errors occurred.  Since
        then, we have (for various reasons) had to introduce the nfs_open_context in
        order to track the file read/write state, and it made sense to move our
        f_error tracking there too.

      [PATCH] block: add unlocked_ioctl support for block devices · bb93e3a5
      Arnd Bergmann authored
      This patch allows block device drivers to convert their ioctl functions to
      unlocked_ioctl() like character devices and other subsystems.  All
      functions that were called with the BKL held before are still used that
      way, but I would not be surprised if it could be removed from the ioctl
      functions in drivers/block/ioctl.c themselves.
      As a side note, I found that compat_blkdev_ioctl() acquires the BKL as
      well, which looks like a bug.  I have checked that every user of
      disk->fops->compat_ioctl() in the current git tree gets the BKL itself, so
      it could easily be removed from compat_blkdev_ioctl().

      [PATCH] fix for prune_icache()/forced final iput() races · 991114c6
      Alexander Viro authored
      Based on analysis and a patch from Russ Weight <rweight@us.ibm.com>
      There is a race condition that can occur if an inode is allocated and then
      released (using iput) during the ->fill_super functions.  The race
      condition is between kswapd and mount.
      For most filesystems this can only happen in an error path when kswapd is
      running concurrently.  For isofs, however, the error can occur in a more
      common code path (which is how the bug was found).
      The logic here is "we want final iput() to free inode *now* instead of
      letting it sit in cache if fs is going down or had not quite come up".  The
      problem is with kswapd seeing such inodes in the middle of being killed and
      happily taking over.
      The clean solution would be to tell kswapd to leave those inodes alone and
      let our final iput deal with them.  I.e.  add a new flag
      (I_FORCED_FREEING), set it before write_inode_now() there and make
      prune_icache() leave those alone.

      [PATCH] libfs: add simple attribute files · acaefc25
      Arnd Bergmann authored
      Based on the discussion about spufs attributes, this is my suggestion
      for a more generic attribute file support that can be used by both
      debugfs and spufs.
      Simple attribute files behave similarly to sequential files from
      a kernel programmers perspective in that a standard set of file
      operations is provided and only an open operation needs to
      be written that registers file specific get() and set() functions.
      These operations are defined as
      void foo_set(void *data, u64 val); and
      u64 foo_get(void *data);
      where data is the inode->u.generic_ip pointer of the file and the
      operations just need to make send of that pointer. The infrastructure
      makes sure this works correctly with concurrent access and partial
      read calls.
      A macro named DEFINE_SIMPLE_ATTRIBUTE is provided to further simplify
      using the attributes.
      This patch already contains the changes for debugfs to use attributes
      for its internal file operations.

      [PATCH] DocBook: changes and extensions to the kernel documentation · 4dc3b16b
      Pavel Pisa authored
      I have recompiled Linux kernel documentation for me and our
      university students again.  The documentation could be extended for more
      sources which are equipped by structured comments for recent 2.6 kernels.  I
      have tried to proceed with that task.  I have done that more times from 2.6.0
      time and it gets boring to do same changes again and again.  Linux kernel
      compiles after changes for i386 and ARM targets.  I have added references to
      some more files into kernel-api book, I have added some section names as well.
       So please, check that changes do not break something and that categories are
      not too much skewed.
      I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
      by kernel convention.  Most of the other changes are modifications in the
      comments to make kernel-doc happy, accept some parameters description and do
      not bail out on errors.  Changed <pid> to @pid in the description, moved some
      #ifdef before comments to correct function to comments bindings, etc.
      You can see result of the modified documentation build at
      Some more sources are ready to be included into kernel-doc generated
      documentation.  Sources has been added into kernel-api for now.  Some more
      section names added and probably some more chaos introduced as result of quick
      cleanup work.

      Linus Torvalds authored
      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!
