Will this affect XFS behaviour with regards to the non-existent Ordered-Mode? -----Original Message----- From: linux-xfs-bounce@xxxxxxxxxxx [mailto:linux-xfs-bounce@xxxxxxxxxxx] On Behalf Of Christoph Hellwig Sent: Wednesday, August 03, 2005 1:59 PM To: linux-xfs@xxxxxxxxxxx; sgi.bugs.xfs@xxxxxxxxxxxxxxxxx Subject: TAKE 934766 - Delay direct I/O completion to a workqueue This is nessecary because aio+dio completions may happen from irq context but we need process context for converting unwritten extents. We also queue regular direct I/O completions to workqueue for regularity, there's only one queue_work call per syscall. |
