This allows fallocate -z to work against a Windows2016 share.
This is due to the SMB3 ZERO_RANGE command does not modify the filesize.
To address this we will now append a compounded SET-INFO to update the
end-of-file information.
This brings xfstests generic/469 closer to working against a windows share.

When we open the shared root handle also ask for FILE_ALL_INFORMATION since
we can do this at zero cost as part of a compound.
Cache this information as long as the lease is held and return and serve any
future requests from cache.
This allows us to serve "stat /<mountpoint>" directly from cache and avoid
a network roundtrip. Since clients often want to do this quite a lot
this improve performance slightly.
As an example: xfstest generic/533 performs 43 stat operations on the root
of the share while it is run. Which are eliminated with this patch.

Since we can now wait for multiple requests atomically in
wait_for_free_request() we can now greatly simplify the handling
of the credits in this function.
This fixes a potential deadlock where many concurrent compound requests
could each have reserved 1 or 2 credits each but are all blocked
waiting for the final credits they need to be able to issue the requests
to the server.
Set a default timeout of 60 seconds for compounded requests.

When the server required encryption (but we didn't connect to it with the

the tcon for that share was encrypted. Similarly we were not displaying
that signing was required when ses->sign was enabled (we only
checked ses->server->sign). This makes it easier to debug when in
fact the connection is signed (or sealed), whether for performance

updates this time around. It's the usual pile of new drivers for new
hardware out there and the normal small fixes and updates, but then we
have some core framework changes too.
In the core framework, we introduce support for a clk_get_optional() API
to get clks that may not always be populated and a way to devm manage clkdev
lookups registered by provider drivers. We also do some refactoring to simplify
the interface between clkdev and the common clk framework so we can reuse the DT
parsing and clk_get() path in provider drivers in the future. This work will
continue in the next few cycles while we convert how providers specify clk
parents.
On the driver side, the biggest part of the dirstat is the Amlogic clk driver
that got support for the G12A SoC. It dominates with almost half the overall
diff, while the second largest part of the diff is in the i.MX clk driver
that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor
and Qualcomm drivers rounding out the big part of the dirstat because they both
got new hardware support for SoCs. The rest is just various updates and non-critical
fixes for existing drivers.
Core:
- Convert a few clk bindings to JSON schema format
- Add a {devm_}clk_get_optional() API
- Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
- Start rewriting clk parent registration and supporting device links
by moving around code that supports clk_get() and DT parsing of the
'clocks' property
New Drivers:
- Add Qualcomm MSM8998 RPM managed clks
- IPA clk support on Qualcomm RPMh clk controllers
- Actions Semi S500 SoC clk support
- Support for fixed rate clks populated from an MMIO register
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
- Add TMU (timer) clocks on Renesas RZ/G2E
- Add Amlogic G12A Always-On Clock Controller
- Add 32k clock generation for Amlogic AXG
- Add support for the Mali GPU clocks on Amlogic Meson8
- Add Amlogic G12A EE clock controller driver
- Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
- Add i.MX8MM SoC clk driver support
Removed Drivers:
- Remove clps711x driver as the board support is gone
Updates:
- 3rd ECO fix for Mediatek MT2712 SoCs
- Updates for Qualcomm MSM8998 GCC clks
- Random static analysis fixes for clk drivers
- Support for sleeping gpios in the clk-gpio type
- Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
- Split LCDC into two clks on the Marvell MMP2 SoC
- Various DT of_node refcount fixes
- Get rid of CLK_IS_BASIC from TI code (yay!)
- TI Autoidle clk support
- Fix Amlogic Meson8 APB clock ID name
- Claim input clocks through DT for Amlogic AXG and GXBB

sk_setup_caps() is called to set sk->sk_dst_cache in pptp_connect,
so we have to dst_release(sk->sk_dst_cache) in pptp_sock_destruct,
otherwise, the dst refcnt will leak.
It can be reproduced by this syz log:
r1 = socket$pptp(0x18, 0x1, 0x2)
bind$pptp(r1, &(0x7f0000000100)={0x18, 0x2, {0x0, @local}}, 0x1e)
connect$pptp(r1, &(0x7f0000000000)={0x18, 0x2, {0x3, @remote}}, 0x1e)

A previous fix ("tls: Fix write space handling") assumed that
user space application gets informed about the socket send buffer
availability when tls_push_sg() gets called. Inside tls_push_sg(), in
case do_tcp_sendpages() returns 0, the function returns without calling
ctx->sk_write_space. Further, the new function tls_sw_write_space()
did not invoke ctx->sk_write_space. This leads to situation that user
space application encounters a lockup always waiting for socket send
buffer to become available.
Rather than call ctx->sk_write_space from tls_push_sg(), it should be
called from tls_write_space. So whenever tcp stack invokes
sk->sk_write_space after freeing socket send buffer, we always declare
the same to user space by the way of invoking ctx->sk_write_space.

It is confusing to directly use return value of netlink_send()/
netlink_unicast() as the return value of *notify*, as it may be not
error at all.
Example: in tc_del_tfilter(), after calling tfilter_del_notify(), it will
goto errout if (err). However, the netlink_send()/netlink_unicast() will
return positive value even for successful case. So it may not call
tcf_chain_tp_remove() and so on to clean up the resource, as a result,
resource is leaked.
It may be easier to only check the return value of tfilter_del_nofiy(),
but it is more clean to correct all related functions.

It has been observed that tx queue may stall while downloading
from certain web sites (example www.speedtest.net)
The cause has been tracked down to a corner case where
the tx interrupt vector was disabled automatically, but
was not re enabled later.
The lan743x has two mechanisms to enable/disable individual
interrupts. Interrupts can be enabled/disabled by individual
source, and they can also be enabled/disabled by individual
vector which has been mapped to the source. Both must be
enabled for interrupts to work properly.
The TX code path, primarily uses the interrupt enable/disable of
the TX source bit, while leaving the vector enabled all the time.
However, while investigating this issue it was noticed that
the driver requested the use of the vector auto clear feature.
The test above revealed a case where the vector enable was
cleared unintentionally.
This patch fixes the issue by deleting the lines that request
the vector auto clear feature to be used.

Merge tag 'libnvdimm-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has been in -next since before the merge window
opened, with no known collisions / issues reported.
The only detail worth noting, outside the summary below, is that the
"libnvdimm-start-pad" topic has been truncated to just cleanups and
small fixes. The full topic branch would have doubled down on hacks
around the "section alignment" limitation of the core-mm, instead
effort is now being spent to address that root issue in the memory
hotplug implementation for v5.2.
- Fix nfit-bus command submission regression
- Support retrieval of short-ARS results if the ARS state is
"requires continuation", and even if the "no_init_ars" module
parameter is specified
- Allow busy-polling of the kernel ARS state by allowing root to
reset the exponential back-off timer
- Filter potentially stale ARS results by tracking query-ARS relative
to the previous start-ARS
- Enhance dax_device alignment checks
- Add support for the Hyper-V family of device-specific-methods
(DSMs)
- Add several fixes and workarounds for Hyper-V compatibility
- Fix support to cache the dirty-shutdown-count at init"
