[LinuxPPS] 3 Feb 19:26 - [PATCH] revert blockdev direct io back to 2.6.19 version

[PATCH] revert blockdev direct io back to 2.6.19 version  
  
Andrew Vasquez is reporting as-iosched oopses and a 65% throughput  
slowdown due to the recent special-casing of direct-io against  
blockdevs. We don't know why either of these things are occurring.  
  
The patch minimally reverts us back to the 2.6.19 code for a 2.6.20  
release.
