Hi Nic, as discussed here is now the third version of the referrals infrastructure. All the configfs layout changes have been removed as requested. Main features of this patchset: - Asynchronous transitioning: I've switched 'transitioning' handling to use a workqueue, that should allow us to simulate asynchronous transitioning modes. IE TCM should now be capable of handling requests while in transitioning, and properly terminate these with the correct sense code. - Include target device descriptor in VPD page 83 For the ALUA device handler we'd need to identify the target device where a given target port belongs to. So include the respective values in the VPD page. - Referrals support: Adding a new configfs attribute 'lba_map' which contains the referrals access mapping. The 'LBD Dependent' ALUA state can only be selected if an lba_map is present; also explicit ALUA has to be disabled. Hannes Reinecke (8): target_core_alua: validate ALUA state transition target_core_alua: Allocate ALUA metadata on demand target_core_alua: store old and pending ALUA state target_core_alua: Use workqueue for ALUA transitioning target_core: simplify scsi_name_len calculation target_core_spc: Include target device descriptor in VPD page 83 target_core_alua: Referrals infrastructure target_core_alua: Referrals configfs integration drivers/target/target_core_alua.c | 546 +++++++++++++++++++++++++++------ drivers/target/target_core_alua.h | 15 +- drivers/target/target_core_configfs.c | 180 ++++++++++- drivers/target/target_core_device.c | 3 + drivers/target/target_core_sbc.c | 5 +- drivers/target/target_core_spc.c | 76 ++++- drivers/target/target_core_transport.c | 28 +- include/scsi/scsi.h | 1 + include/target/target_core_base.h | 27 +- 9 files changed, 770 insertions(+), 111 deletions(-) -- 1.7.12.4 -- 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
