      9p: Include fsync support for 9p client · 7a4439c4
      M. Mohan Kumar authored
      
      
      Implement the fsync in the client side by marking stat field values to 'don't touch' so that server may 
      interpret it as a request to guarantee that the contents of the associated file are committed to stable 
      storage before the Rwstat message is returned.
      
      Without this patch, calling fsync on a 9p file results in "Invalid argument" error. Please check the attached 
      C program.

      9p: fix O_APPEND in legacy mode · 2e4bef41
      Eric Van Hensbergen authored
      
      
      The legacy protocol's open operation doesn't handle an append operation
      (it is expected that the client take care of it).  We were incorrectly
      passing the extended protocol's flag through even in legacy mode.  This
      was reported in bugzilla report #10689.  This patch fixes the problem
      by disallowing extended protocol open modes from being passed in legacy
      mode and implemented append functionality on the client side by adding
      a seek after the open.

      9p: implement optional loose read cache · e03abc0c
      Eric Van Hensbergen authored
      
      
      While cacheing is generally frowned upon in the 9p world, it has its
      place -- particularly in situations where the remote file system is
      exclusive and/or read-only.  The vacfs views of venti content addressable
      store are a real-world instance of such a situation.  To facilitate higher
      performance for these workloads (and eventually use the fscache patches),
      we have enabled a "loose" cache mode which does not attempt to maintain
      any form of consistency on the page-cache or dcache.  This results in over
      two orders of magnitude performance improvement for cacheable block reads
      in the Bonnie benchmark.  The more aggressive use of the dcache also seems
      to improve metadata operational performance.

      [PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait) · 28fd1298
      OGAWA Hirofumi authored
      
      
      This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it.
      
      See mm/filemap.c:
      
      And changes the filemap_write_and_wait() and filemap_write_and_wait_range().
      
      Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite()
      returns error.  However, even if filemap_fdatawrite() returned an
      error, it may have submitted the partially data pages to the device.
      (e.g. in the case of -ENOSPC)
      
      <quotation>
      Andrew Morton writes,
      
      If filemap_fdatawrite() returns an error, this might be due to some
      I/O problem: dead disk, unplugged cable, etc.  Given the generally
      crappy quality of the kernel's handling of such exceptions, there's a
      good chance that the filemap_fdatawait() will get stuck in D state
      forever.
      </quotation>
      
      So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO.
      
      Trond, could you please review the nfs part?  Especially I'm not sure,
      nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

      [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason · 733482e4
      Olaf Hering authored
      
      
      This patch removes almost all inclusions of linux/version.h.  The 3
      #defines are unused in most of the touched files.
      
      A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
      unfortunatly in linux/version.h.
      
      There are also lots of #ifdef for long obsolete kernels, this was not
      touched.  In a few places, the linux/version.h include was move to where
      the LINUX_VERSION_CODE was used.
      
      quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`
      
      search pattern:
      /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h
