* tag 'nvme-6.9-2024-03-21' of git://git.infradead.org/nvme:
  nvmet-rdma: remove NVMET_RDMA_REQ_INVALIDATE_RKEY flag
  nvme: remove redundant BUILD_BUG_ON check
  nvme/tcp: Add wq_unbound modparam for nvme_tcp_wq
  nvme-tcp: Export the nvme_tcp_wq to sysfs
  drivers/nvme: Add quirks for device 126f:2262
  nvme: parse format command's lbafu when tracing
  nvme: add tracing of reservation commands
  nvme: parse zns command's zsa and zrasf to string
  nvme: use nvme_disk_is_ns_head helper
  nvme: fix reconnection fail due to reserved tag allocation
  nvmet: add tracing of zns commands
  nvmet: add tracing of authentication commands
  nvme-apple: Convert to platform remove callback returning void
  nvmet-tcp: do not continue for invalid icreq
  nvme: change shutdown timeout setting message

We can simply use invalidate_rkey to check instead of adding a flag.

Remove redundant BUILD_BUG_ON check of struct nvme_dsm_range, it's
already checked in nvme_init_ctrl().

The default nvme_tcp_wq will use all CPUs to process tasks. Sometimes it is
necessary to set CPU affinity to improve performance.

A new module parameter wq_unbound is added here. If set to true, users can
configure cpu affinity through
/sys/devices/virtual/workqueue/nvme_tcp_wq/cpumask.

This commit adds NVME_QUIRK_NO_DEEPEST_PS and NVME_QUIRK_BOGUS_NID for
device [126f:2262], which appears to be a generic VID:PID pair used for
many SSDs based on the Silicon Motion SM2262/SM2262EN controller.

Two of my SSDs with this VID:PID pair exhibit the same behavior:

  * They frequently have trouble exiting the deepest power state (5),
    resulting in the entire disk unresponsive.
    Verified by setting nvme_core.default_ps_max_latency_us=10000 and
    observing them behaving normally.
  * They produce all-zero nguid and eui64 with `nvme id-ns` command.

The offending products are:

  * HP SSD EX950 1TB
  * HIKVISION C2000Pro 2TB

Use nvme_disk_is_ns_head helper instead of check fops directly,
and also drop CONFIG_NVME_MULTIPATH check.
