From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> Hi folks, Here's the first pass of a nvmet multi-tenant configfs layout, following what we've learned in target_core_fabric_configfs.c wrt to independent operation of storage endpoints. Here is how the running RFC-v1 code currently looks: /sys/kernel/config/nvmet/subsystems/ └── nqn.2003-01.org.linux-iscsi.NVMf.skylake-ep ├── namespaces │ └── 1 │ └── ramdisk0 -> ../../../../../target/core/rd_mcp_1/ramdisk0 └── ports └── loop ├── addr_adrfam ├── addr_portid ├── addr_traddr ├── addr_treq ├── addr_trsvcid ├── addr_trtype └── enable Namely, it allows existing /sys/kernel/config/target/core/ backends to be configfs symlinked into ../nvmet/subsystems/$SUBSYS_NQN/ as nvme namespaces. The series exposes T10-PI from /sys/kernel/config/target/core/ as ID_NS.ms + ID_NS.dps feature bits, and enables block integrity support with nvme/loop driver. Note this series depends upon the following prerequisites of target-core: http://marc.info/?l=linux-scsi&m=146527281416606&w=2 and of course, today's earlier release of nvmet + friends: http://lists.infradead.org/pipermail/linux-nvme/2016-June/004754.html Note the full set of patches is available from: https://git.kernel.org/cgit/linux/kernel/git/nab/target-pending.git/log/?h=nvmet-configfs-ng Comments..? --nab Nicholas Bellinger (8): nvmet: Add nvmet_fabric_ops get/put transport helpers nvmet: Add support for configfs-ng multi-tenant logic nvmet: Hookup nvmet_ns->dev to nvmet_ns_enable nvmet/io-cmd: Hookup sbc_ops->execute_rw backend ops nvmet/io-cmd: Hookup sbc_ops->execute_sync_cache backend ops nvmet/io-cmd: Hookup sbc_ops->execute_unmap backend ops nvmet/admin-cmd: Hookup T10-PI to ID_NS.ms + ID_NS.dps feature bits nvme/loop: Add support for bio integrity handling drivers/nvme/target/Makefile | 2 +- drivers/nvme/target/admin-cmd.c | 17 ++ drivers/nvme/target/configfs-ng.c | 585 ++++++++++++++++++++++++++++++++++++++ drivers/nvme/target/configfs.c | 5 +- drivers/nvme/target/core.c | 83 +++--- drivers/nvme/target/io-cmd.c | 169 ++++++----- drivers/nvme/target/loop.c | 19 ++ drivers/nvme/target/nvmet.h | 27 +- 8 files changed, 799 insertions(+), 108 deletions(-) create mode 100644 drivers/nvme/target/configfs-ng.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
