I would say it is a "large attribute" not "large numbers of attributes". > > configfs has the same "one value per file" rule that sysfs has.

We decided to use an existing infrastructure instead of having our own file system. configfs is a perfect fit for us, except the size limitation. BTW, it it not just CKRM/RG, Paul Menage as recently extracted the processes aggregation from cpuset to have an independent infrastructure (http://marc.theaimsgroup.com/?l=ckrm-tech&m=116006307018720&w=2), which has its own file system. I was advocating him to use configfs. But, he also has this issue/limitation. > > thanks, > > greg k-h -- ---------------------------------------------------------------------- Chandra Seetharaman | Be careful what you choose.... - [EMAIL PROTECTED] | .......you may get it. ---------------------------------------------------------------------- ------------------------------------------------------------------------- Using Tomcat but need to do more?
