This time with dev_loss_tmo active with SCSI and NVME enabled on the same rport. Nothing exploded, all resources were released correctly. I am not so happy with the 'connect_sync' name yet (patch #1) but we still have to agree on that offloading the initial connect attemp is correct. James and Hannes are strongly in favour for this approach as far I can tell. changes: v1: - renamed 'nvme-fc: redesign locking and refcounting' to 'nvme-fc: reorder ctrl ref counting and cleanup code path' - testing with scsi/nvme dev_loss_tmo on real hw - removed rport ref counting part - collected RB tags v0: - initial version - https://lore.kernel.org/linux-nvme/20240216084526.14133-1-dwagner@suse.de/ Daniel Wagner (6): nvme-fabrics: introduce connect_sync option nvme-fc: rename free_ctrl callback to match name pattern nvme-fc: do not retry when auth fails or connection is refused nvme-fabrics: introduce ref counting for nvmf_ctrl_options nvme-fc: reorder ctrl ref counting and cleanup code path nvme-fc: wait for connect attempt to finish drivers/nvme/host/fabrics.c | 28 ++++++- drivers/nvme/host/fabrics.h | 9 ++- drivers/nvme/host/fc.c | 145 +++++++++++++++++------------------- drivers/nvme/host/rdma.c | 18 +++-- drivers/nvme/host/tcp.c | 21 ++++-- drivers/nvme/target/loop.c | 19 +++-- 6 files changed, 141 insertions(+), 99 deletions(-) -- 2.43.1
