      [PATCH] splice: fix page stealing LRU handling. · 3e7ee3e7
      Jens Axboe authored
      Originally from Nick Piggin, just adapted to the newer branch.
      You can't check PageLRU without holding zone->lru_lock.  The page
      release code can get away with it only because the page refcount is 0 at
      that point. Also, you can't reliably remove pages from the LRU unless
      the refcount is 0. Ever.

      [PATCH] splice: page stealing needs to wait_on_page_writeback() · ad8d6f0a
      Jens Axboe authored
      Thanks to Andrew for the good explanation of why this is so. akpm writes:
      If a page is under writeback and we remove it from pagecache, it's still
      going to get written to disk.  But the VFS no longer knows about that page,
      nor that this page is about to modify disk blocks.
      So there might be scenarios in which those
      blocks-which-are-about-to-be-written-to get reused for something else.
      When writeback completes, it'll scribble on those blocks.
      This won't happen in ext2/ext3-style filesystems in normal mode because the
      page has buffers and try_to_release_page() will fail.
      But ext2 in nobh mode doesn't attach buffers at all - it just sticks the
      page in a BIO, finds some new blocks, points the BIO at those blocks and
      lets it rip.
      While that write IO's in flight, someone could truncate the file.  Truncate
      won't block on the writeout because the page isn't in pagecache any more.
      So truncate will the free the blocks from the file under the page's feet.
      Then something else can reallocate those blocks.  Then write data to them.
      Now, the original write completes, corrupting the filesystem.

      [PATCH] splice: improve writeback and clean up page stealing · 4f6f0bd2
      Jens Axboe authored
      By cleaning up the writeback logic (killing write_one_page() and the manual
      set_page_dirty()), we can get rid of ->stolen inside the pipe_buffer and
      just keep it local in pipe_to_file().
      This also adds dirty page balancing logic and O_SYNC handling.

      [PATCH] revert incorrect mutex conversion in hdaps driver · 597a7679
      Arjan van de Ven authored
      This reverts the mutex conversion that was recently done to the hdaps
      driver; this coversion was buggy because the hdaps driver started using
      this semaphore in IRQ context, which mutexes do not allow.  Easiest
      solution for now is to just revert the patch (the patch was part of a
      bigger GIT commit, 9a61bf63
       but this
      only reverts this one file)

      [PATCH] sbp2: fix spinlock recursion · 24c7cd06
      Stefan Richter authored
      sbp2util_mark_command_completed takes a lock which was already taken by
      sbp2scsi_complete_all_commands.  This is a regression in Linux 2.6.15.
       Reported by Kristian Harms at
      [ More complete commentary, as response to questions by Andrew: ]
      > This changes the call environment for all implementations of
      > ->Current_done().  Are they all safe to call under this lock?
      Short answer: Yes, trust me.  ;-) Long answer:
      The done() callbacks are passed on to sbp2 from the SCSI stack along
      with each SCSI command via the queuecommand hook.  The done() callback
      is safe to call in atomic context.  So does
      Documentation/scsi/scsi_mid_low_api.txt say, and many if not all SCSI
      low-level handlers rely on this fact.  So whatever this callback does,
      it is "self-contained" and it won't conflict with sbp2's internal ORB
      list handling.  In particular, it won't race with the
      Moreover, sbp2 already calls the done() handler with
      sbp2_command_orb_lock taken in sbp2scsi_complete_all_commands().  I
      admit this is ultimately no proof of correctness, especially since this
      portion of code introduced the spinlock recursion in the first place and
      we didn't realize it since this code's submission before 2.6.15 until
      now.  (I have learned a lesson from this.)
      I stress-tested my patch on x86 uniprocessor with a preemptible SMP
      kernel (alas I have no SMP machine yet) and made sure that all code
      paths which involve the sbp2_command_orb_lock were gone through multiple
