As different nvme controllers are connect via different fabrics, some require different timeout settings than others. This series implements per-controller timeouts in the nvme subsystem which can be set via sysfs.
We have reached out to the NVMe working group to implement per-controller timeout values. These patches are paving the way for this. Changes since v1: - implement the change not only for the pci NVMe driver but also for fc, lightnvm, rdma, tcp and loop. - add an additional check when updating timeouts to not race with controller creation or deletion Maximilian Heyne (2): nvme: add per-controller io and admin timeouts nvme: add sysfs controls for io and admin timeouts drivers/nvme/host/core.c | 123 +++++++++++++++++++++++++++++++++++++++++-- drivers/nvme/host/fc.c | 2 +- drivers/nvme/host/lightnvm.c | 2 +- drivers/nvme/host/nvme.h | 2 + drivers/nvme/host/pci.c | 13 ++--- drivers/nvme/host/rdma.c | 4 +- drivers/nvme/host/tcp.c | 4 +- drivers/nvme/target/loop.c | 4 +- 8 files changed, 136 insertions(+), 18 deletions(-) -- 2.16.5 Amazon Development Center Germany GmbH Krausenstr. 38 10117 Berlin Geschaeftsfuehrer: Christian Schlaeger, Ralf Herbrich Ust-ID: DE 289 237 879 Eingetragen am Amtsgericht Charlottenburg HRB 149173 B
