  Hello,

  this is second iteration of patches to fix handling of O_SYNC AIO DIO.
Since previous version I've addressed Dave's comments:
 - slightly expanded changelog of the first patch
 - workqueue is now created with parameters allowing paralelism
 - workqueue name contains sb->s_id
 - workqueue is created on demand (I decided to do this to reduce the overhead
   in unnecessary cases)

The patchset survives xfstests run for ext4 & xfs so it should be sane. Since
this touches several filesystems (although only ext4 & xfs are non-trivial),
the question is who should carry these patches. Maybe Al? But since xfs and
ext4 changes are non-trivial, I'd like to have a review from their
developers...
