I think you misunderstood Brian, the server patches aren't really "general performance" patches, they are specific to Lustre and the mainline kernel people won't accept patches like that without an in-kernel user among other reasons... The ldiskfs work is being integrated and forms a large chunk of ext4. > Would there be significant performance loss if the server would be moved > completely to the user space and then there would be minimum problems with > kernels. That is/was the plan last time I heard... not sure what the current status is... search bugzilla for uoss/umds _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
