Hi Jens, please pull this first batch of nvme updates for Linux 4.21. Highlights: - target support for persistent discovery controllers (Jay Sternberg) - target optimizations to use non-blocking reads (Chaitanya Kulkarni) - host side support for the Enhanced Command Retry TP (Keith Busch) - host and target support for traffic based keep alive (Sagi Grimberg) - host and target support for disabling SQ based flow control (Sagi Grimberg) Plus all kinds of optimizations and cleanups from the usual suspects. The following changes since commit 43e497feb3987c868f87c7ca1470c5937689fe01: blk-mq: re-build queue map in case of kdump kernel (2018-12-06 22:52:59 -0700) are available in the Git repository at: git://git.infradead.org/nvme.git nvme-4.21 for you to fetch changes up to 48fd68b3c5c66af6e0004787a54765a8d040989b: nvme: remove unused function nvme_ctrl_ready (2018-12-07 11:16:38 -0800) ---------------------------------------------------------------- Chaitanya Kulkarni (4): nvme: consolidate memset calls in the nvme_setup_cmd path nvmet: use IOCB_NOWAIT for file-ns buffered I/O nvmet: use unlikely for req status check nvmet: fix the structure member indentation Christoph Hellwig (1): nvmet: mark nvmet_genctr static Hannes Reinecke (1): nvme: add a numa_node field to struct nvme_ctrl Israel Rukshin (3): nvme: Remove unused forward declaration nvmet-rdma: Add unlikely for response allocated check nvme: remove unused function nvme_ctrl_ready James Smart (1): nvmet-fc: remove the IN_ISR deferred scheduling options Jay Sternberg (7): nvmet: provide aen bit functions for multiple controller types nvmet: change aen mask functions to use bit numbers nvmet: allow Keep Alive for Discovery controller nvmet: make kato and AEN processing for use by other controllers nvmet: add defines for discovery change async events nvmet: add support to Discovery controllers for commands nvmet: enable Discovery Controller AENs Keith Busch (1): nvme: implement Enhanced Command Retry Sagi Grimberg (9): nvme: introduce ctrl attributes enumeration nvme: cache controller attributes nvme: support traffic based keep-alive nvmet: support for traffic based keep-alive nvmet: allow host connect even if no allowed subsystems are exported nvmet: support fabrics sq flow control nvmet: don't override treq upon modification. nvmet: expose support for fabrics SQ flow control disable in treq nvme: disable fabrics SQ flow control when asked by the user drivers/nvme/host/core.c | 70 ++++++++++++++++++-- drivers/nvme/host/fabrics.c | 13 +++- drivers/nvme/host/fabrics.h | 2 + drivers/nvme/host/fc.c | 5 +- drivers/nvme/host/multipath.c | 4 +- drivers/nvme/host/nvme.h | 13 ++-- drivers/nvme/host/rdma.c | 5 +- drivers/nvme/target/admin-cmd.c | 76 ++++++++++++---------- drivers/nvme/target/configfs.c | 42 ++++++++---- drivers/nvme/target/core.c | 118 +++++++++++++--------------------- drivers/nvme/target/discovery.c | 129 +++++++++++++++++++++++++++++++++++-- drivers/nvme/target/fabrics-cmd.c | 6 ++ drivers/nvme/target/fc.c | 66 +------------------ drivers/nvme/target/io-cmd-file.c | 130 ++++++++++++++++++++++++-------------- drivers/nvme/target/nvmet.h | 53 +++++++++++++--- drivers/nvme/target/rdma.c | 2 +- include/linux/nvme-fc-driver.h | 16 ----- include/linux/nvme.h | 51 +++++++++++++-- 18 files changed, 514 insertions(+), 287 deletions(-)
