lustre/kernel_patches/patches/export-2.6.18-vanilla.patch

   1 Allow starting the commit of a journal transaction, without waiting for
   2 it to complete.  This is a performance enhancement for OST IO so that
   3 the journal commit can run concurrently with the file IO.  It isn't
   4 necessary if the client can handle bulk IO recovery (bug 16919).
