Pure nfs client performance using odirect. When an application opens a file with O_DIRECT flag, if the size of the data that is written is equal to wsize, the client sends a WRITE RPC with stable flag set to UNSTABLE followed by a single COMMIT RPC rather than sending a single WRITE RPC with the stable flag set to FILE_SYNC. This a bug. Patch to fix this. Signed-off-by: Arun R Bharadwaj <arun@linux.vnet.ibm.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
