The disk scheduler is knocked out of the picture unless it can see the IO generated by each group above it. The world of memcg-aware writeback stacked on top of block-cgroups is a complicated one. Throttling in balance_dirty_pages() will likely be a non-starter for current users of group-aware CFQ. I'd like a discussion that covers the system-wide view of: memory -> memcg groups -> block cgroups -> multiple block devices Chad On Mon, Mar 28, 2011 at 9:36 PM, James Bottomley wrote: > Hi All, > > Since LSF is less than a week away, the programme committee put toget= her > a just in time preliminary agenda for LSF. =A0As you can see there is > still plenty of empty space, which you can make suggestions (to this > list with appropriate general list cc's) for filling: > > https://spreadsheets.google.com/pub?hl=3Den&hl=3Den&key=3D0AiQMl7GcVa= 7OdFdNQzM5UDRXUnVEbHlYVmZUVHQ2amc&output=3Dhtml > > If you don't make suggestions, the programme committee will feel > empowered to make arbitrary assignments based on your topic and atten= dee > email requests ... > > We're still not quite sure what rooms we will have at the Kabuki, but > we'll add them to the spreadsheet when we know (they should be close = to > each other). > > The spreadsheet above also gives contact information for all the > attendees and the programme committee. > > Yours, > > James Bottomley > on behalf of LSF/MM Programme Committee > > > _______________________________________________ > Lsf mailing list > Lsf@lists.linux-foundation.org > https://lists.linux-foundation.org/mailman/listinfo/lsf > -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel= " in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
