Hello Linus,
Here is my PR for the v7.0 kernel. It includes fixes, cleanups, and
support for a new Intel NTB. The patches have been in my tree for some
time, though the tag is new. Please consider pulling them.
Thanks,
Jon

NTB: ntb_transport: Use seq_file for QP stats debugfs (2026-02-20 17:31:55 -0500)
----------------------------------------------------------------
NTB updates include debugfs improvements, correctness fixes,
cleanups, and new hardware support. ntb_transport QP stats are
converted to seq_file, a tx_memcpy_offload module parameter is
introduced with associated ordering fixes, and a debugfs queue
name truncation bug is corrected. Additional fixes address format
specifier mismatches in ntb_tool and boundary conditions in the
Switchtec driver, while unused MSI helpers are removed and the
codebase migrates to dma_map_phys(). Intel Gen6 (Diamond Rapids)
NTB support is also added.
