Date: Sun, 21 Mar 2010 23:17:26 -0400 Message-ID: <4BA6E146.10709@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 To: linux-btrfs Return-path: List-ID: Here is the complete direct I/O read patch series rebased onto the current btrfs-unstable and tested against 2.6.33. I have not done clean up of the diocb/extcb and did not simplify the user memory handling yet. There still is a problem with the wakeup of the submit thread in btrfs_dio_wait(). With fsx on a 2-core x86-64 it will eventually hang, as in within 2 hours. Either I am missing the wakeup or miscounting the done state and going back to sleep with all I/O finished. jim
