RHEL 6.0 released with RH kernel 2.6.32-71 and it *does* contain the commit acdc53b2 "NFS: Replace __nfs_write_mapping with sync_inode()" backported to 2.6.32. So, I doubt that the reported bad Fedora performance is due to that commit. cya, # -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
