kernel/bpf/inode.c misuses kern_path...() - it's much simpler (and
more efficient, on top of that) to use user_path...() counterparts
rather than bothering with doing getname() manually.

net: hns3: misc updates for -net-next
This series includes some misc updates for the HNS3 ethernet driver.
[patch 1] adds a limitation for the error log in the
hns3_clean_tx_ring().
[patch 2] adds a check for pfmemalloc flag before reusing pages
since these pages may be used some special case.
[patch 3] assigns a default reset type 'HNAE3_NONE_RESET' to
VF's reset_type after initializing or reset.
[patch 4] unifies macro HCLGE_DFX_REG_TYPE_CNT's definition into
header file.
[patch 5] refines the parameter 'size' of snprintf() in the

The function snprintf() writes at most size bytes (including the
terminating null byte ('\0') to str. Now, We can guarantee that the
parameter of size is lager than the length of str to be formatting
including its terminating null byte. So it's unnecessary to minus 1
for the input parameter 'size'.

HNS3 driver allocates pages for DMA with dev_alloc_pages(), which
calls alloc_pages_node() with the __GFP_MEMALLOC flag. So, in case
of OOM condition, HNS3 can get pages with pfmemalloc flag set.
So do not reuse the pages with pfmemalloc flag set because those
pages are reserved for special cases, such as low memory case.

====================
Use ODP MRs for kernel ULPs
The following series extends MR creation routines to allow creation of
user MRs through kernel ULPs as a proxy. The immediate use case is to
allow RDS to work over FS-DAX, which requires ODP (on-demand-paging)
MRs to be created and such MRs were not possible to create prior this
series.
The first part of this patchset extends RDMA to have special verb
ib_reg_user_mr(). The common use case that uses this function is a
userspace application that allocates memory for HCA access but the
responsibility to register the memory at the HCA is on an kernel ULP.
This ULP acts as an agent for the userspace application.
The second part provides advise MR functionality for ULPs. This is
integral part of ODP flows and used to trigger pagefaults in advance
to prepare memory before running working set.
The third part is actual user of those in-kernel APIs.

Toke Høiland-Jørgensen says:
====================
We are currently being somewhat inconsistent with the libbpf include paths,
which makes it difficult to move files from the kernel into an external
libbpf-using project without adjusting include paths.
Having the bpf/ subdir of $INCLUDEDIR in the include path has never been a
requirement for building against libbpf before, and indeed the libbpf pkg-config
file doesn't include it. So let's make all libbpf includes across the kernel
tree use the bpf/ prefix in their includes. Since bpftool skeleton generation
emits code with a libbpf include, this also ensures that those can be used in
existing external projects using the regular pkg-config include path.
This turns out to be a somewhat invasive change in the number of files touched;
however, the actual changes to files are fairly trivial (most of them are simply
made with 'sed'). The series is split to make the change for one tool subdir at
a time, while trying not to break the build along the way. It is structured like
this:
- Patch 1-3: Trivial fixes to Makefiles for issues I discovered while changing
the include paths.
- Patch 4-8: Change the include directives to use the bpf/ prefix, and updates
Makefiles to make sure tools/lib/ is part of the include path, but without
removing tools/lib/bpf
- Patch 9-11: Remove tools/lib/bpf from include paths to make sure we don't
inadvertently re-introduce includes without the bpf/ prefix.
Changelog:
v5:
- Combine the libbpf build rules in selftests Makefile (using Andrii's
suggestion for a make rule).
- Re-use self-tests libbpf build for runqslower (new patch 10)
- Formatting fixes
v4:
- Move runqslower error on missing BTF into make rule
- Make sure we don't always force a rebuild selftests
- Rebase on latest bpf-next (dropping patch 11)
v3:
- Don't add the kernel build dir to the runqslower Makefile, pass it in from
selftests instead.
- Use libbpf's 'make install_headers' in selftests instead of trying to
generate bpf_helper_defs.h in-place (to also work on read-only filesystems).
- Use a scratch builddir for both libbpf and bpftool when building in selftests.
- Revert bpf_helpers.h to quoted include instead of angled include with a bpf/
prefix.
- Fix a few style nits from Andrii
v2:
- Do a full cleanup of libbpf includes instead of just changing the
bpf_helper_defs.h include.

To make sure no new files are introduced that doesn't include the bpf/
prefix in its #include, remove tools/lib/bpf from the include path
entirely.
Instead, we introduce a new header files directory under the scratch tools/
dir, and add a rule to run the 'install_headers' rule from libbpf to have a
full set of consistent libbpf headers in $(OUTPUT)/tools/include/bpf, and
then use $(OUTPUT)/tools/include as the include path for selftests.
For consistency we also make sure we put all the scratch build files from
other bpftool and libbpf into tools/build/, so everything stays within
selftests/.

The runqslower tool refuses to build without a file to read vmlinux BTF
from. The build fails with an error message to override the location by
setting the VMLINUX_BTF variable if autodetection fails. However, the
Makefile doesn't actually work with that override - the error message is
still emitted.
Fix this by including the value of VMLINUX_BTF in the expansion, and only
emitting the error message if the *result* is empty. Also permit running
'make clean' even though no VMLINUX_BTF is set.

The 'clean' rule in the samples/bpf Makefile tries to remove backup

to remove the user's home directory. While the attempt is mostly harmless,
it does lead to a somewhat scary warning like this:
rm: cannot remove '~': Is a directory

mlxsw: Adjust SPAN egress mirroring buffer size handling for Spectrum-2
Jiri says:
For Spectrum-2 the computation of SPAN egress mirroring buffer uses a
different formula. On top of MTU it needs also current port speed. Fix
the computation and also trigger the buffer size set according to PUDE
event, which happens when port speed changes.

When PUDE event is handled and the link is up, update the port SPAN
buffer size according to the current speed.

For SPAN egress mirroring buffer size, it is needed to use a different
formula for Spectrum and Spectrum-2. Move the buffer size computation to
ops and implement new formula for Spectrum-2.

Avoid duplication of code that is doing buffsize update and put it into
a separate helper function.

Currently PTP code queries directly PTYS register for port speed from
work scheduled upon PUDE event. Since the speed needs to be used for
SPAN buffer size computation as well, push the code into a separate
helper.

net: phy: add generic ndo_do_ioctl handler phy_do_ioctl
A number of network drivers has the same glue code to use phy_mii_ioctl
as ndo_do_ioctl handler. So let's add such a generic ndo_do_ioctl
handler to phylib. As first user convert r8169.

Replace rtl8169_ioctl with new generic function phy_do_ioctl.

The SERDES statistics are valid for all members of the 6390 family,
not just the 6390 itself. Add the needed callbacks to all members of
the family.
