Revision 8f676b8508c250bbe255096522fdefb73f1ea0b9 authored by Sagi Grimberg on 02 November 2018, 18:22:13 UTC, committed by Jens Axboe on 09 November 2018, 13:14:47 UTC
Whenever we update ns_head info, we need to make sure it is still compatible with all underlying backing devices because although nvme multipath doesn't have any explicit use of these limits, other devices can still be stacked on top of it which may rely on the underlying limits. Start with unlimited stacking limits, and every info update iterate over siblings and adjust queue limits.
