It's somewhat unfortunate but with (my?) the current tooling
if people post new versions of a set in reply to an old version
managing the review queue gets difficult. So recommend against it.

Commit b655892ffd6d ("leds: trigger: netdev: expose hw_control status
via sysfs") exposed to sysfs the flag that tells whether the LED trigger
is offloaded to hardware, under the name "hw_control", since that is the
name under which this setting is called in the code.
Everywhere else in kernel when some work that is normally done in
software can be made to be done by hardware instead, we use the word
"offloading" to describe this, e.g. "LED blinking is offloaded to
hardware".
Normally renaming sysfs entries is a no-go because of backwards
compatibility. But since this patch was not yet released in a stable
kernel, I think it is still possible to rename it, if there is
consensus.

Improve aRFS observability by adding new set of counters. Each Rx
ring will have this set of counters listed below.
These counters are exposed through ethtool -S.
1) arfs_add: number of times a new rule has been created.
2) arfs_request_in: number of times a rule was requested to move from
its current Rx ring to a new Rx ring (incremented on the destination
Rx ring).
3) arfs_request_out: number of times a rule was requested to move out
from its current Rx ring (incremented on source/current Rx ring).
4) arfs_expired: number of times a rule has been expired by the
kernel and removed from HW.
5) arfs_err: number of times a rule creation or modification has
failed.
This patch removes rx[i]_xsk_arfs_err counter and its documentation in
mlx5/counters.rst since aRFS activity does not occur in XSK RQ's.

In SCTP protocol, it is using the same timer (T2 timer) for SHUTDOWN and
SHUTDOWN_ACK retransmission. However in sctp conntrack the default timeout
value for SCTP_CONNTRACK_SHUTDOWN_ACK_SENT state is 3 secs while it's 300
msecs for SCTP_CONNTRACK_SHUTDOWN_SEND/RECV state.
As Paolo Valerio noticed, this might cause unwanted expiration of the ct
entry. In my test, with 1s tc netem delay set on the NAT path, after the
SHUTDOWN is sent, the sctp ct entry enters SCTP_CONNTRACK_SHUTDOWN_SEND
state. However, due to 300ms (too short) delay, when the SHUTDOWN_ACK is
sent back from the peer, the sctp ct entry has expired and been deleted,
and then the SHUTDOWN_ACK has to be dropped.
Also, it is confusing these two sysctl options always show 0 due to all
timeout values using sec as unit:
net.netfilter.nf_conntrack_sctp_timeout_shutdown_recd = 0
net.netfilter.nf_conntrack_sctp_timeout_shutdown_sent = 0
This patch fixes it by also using 3 secs for sctp shutdown send and recv
state in sctp conntrack, which is also RTO.initial value in SCTP protocol.
Note that the very short time value for SCTP_CONNTRACK_SHUTDOWN_SEND/RECV
was probably used for a rare scenario where SHUTDOWN is sent on 1st path
but SHUTDOWN_ACK is replied on 2nd path, then a new connection started
immediately on 1st path. So this patch also moves from SHUTDOWN_SEND/RECV
to CLOSE when receiving INIT in the ORIGINAL direction.

A new check for the tx devlink health reporter is introduced for
determining when the PTP port timestamping SQ is considered unhealthy. If
there are enough CQEs considered never to be delivered, the space that can
be utilized on the SQ decreases significantly, impacting performance and
usability of the SQ. The health reporter is triggered when the number of
likely never delivered port timestamping CQEs that utilize the space of the
PTP SQ is greater than 93.75% of the total capacity of the SQ. A devlink
health reporter recover method is also provided for this specific TX error
context that restarts the PTP SQ.

Use a map structure for associating CQEs containing port timestamping
information with the appropriate skb. Track order of WQEs submitted using a
FIFO. Check if the corresponding port timestamping CQEs from the lookup
values in the FIFO are considered dropped due to time elapsed. Return the
lookup value to a freelist after consuming the skb. Reuse the freed lookup
in future WQE submission iterations.
The map structure uses an integer identifier for the key and returns an skb
corresponding to that identifier. Embed the integer identifier in the WQE
submitted to the WQ for the transmit path when the SQ is a PTP (port
timestamping) SQ. The embedded identifier can then be queried using a field
in the CQE of the corresponding port timestamping CQ. In the port
timestamping napi_poll context, the identifier is queried from the CQE
polled from CQ and used to lookup the corresponding skb from the WQE submit
path. The skb reference is removed from map and then embedded with the port
HW timestamp information from the CQE and eventually consumed.
The metadata freelist FIFO is an array containing integer identifiers that
can be pushed and popped in the FIFO. The purpose of this structure is
bookkeeping what identifier values can safely be used in a subsequent WQE
submission and should not contain identifiers that have still not been
reaped by processing a corresponding CQE completion on the port
timestamping CQ.
The ts_cqe_pending_list structure is a combination of an array and linked
list. The array is pre-populated with the nodes that will be added and
removed from the head of the linked list. Each node contains the unique
identifier value associated with the values submitted in the WQEs and
retrieved in the port timestamping CQEs. When a WQE is submitted, the node
in the array corresponding to the identifier popped from the metadata
freelist is added to the end of the CQE pending list and is marked as
"in-use". The node is removed from the linked list under two conditions.
The first condition is that the corresponding port timestamping CQE is
polled in the PTP napi_poll context. The second condition is that more than
a second has elapsed since the DMA timestamp value corresponding to the WQE
submission. When the first condition occurs, the "in-use" bit in the linked
list node is cleared, and the resources corresponding to the WQE submission
are then released. The second condition, however, indicates that the port
timestamping CQE will likely never be delivered. It's not impossible for
the device to post a CQE after an infinite amount of time though highly
improbable. In order to be resilient to this improbable case, resources
related to the corresponding WQE submission are still kept, the identifier
value is not returned to the freelist, and the "in-use" bit is cleared on
the node to indicate that it's no longer part of the linked list of "likely
to be delivered" port timestamping CQE identifiers. A count for the number
of port timestamping CQEs considered highly likely to never be delivered by
the device is maintained. This count gets decremented in the unlikely event
a port timestamping CQE considered unlikely to ever be delivered is polled
in the PTP napi_poll context.

In commit 82e896d992fa ("docs: net: page_pool: use kdoc to avoid
duplicating the information") I shied away from using the DOC:
comments when moving to kdoc for documenting page_pool API,
because I wasn't sure how familiar people are with it.
Turns out there is already a DOC: comment for the intro, which
is the same in both places, modulo what looks like minor rewording.
Use the version from Documentation/ but keep the contents with
the code.

Split types and pure function declarations from page_pool.h
and add them in page_page/types.h, so that C sources can
include page_pool.h and headers should generally only include
page_pool/types.h as suggested by jakub.
Rename page_pool.h to page_pool/helpers.h to have both in
one place.

All users now just use '->iterate_shared()', which only takes the
directory inode lock for reading.
Filesystems that never got convered to shared mode now instead use a
wrapper that drops the lock, re-takes it in write mode, calls the old
function, and then downgrades the lock back to read mode.
This way the VFS layer and other callers no longer need to care about
filesystems that never got converted to the modern era.
The filesystems that use the new wrapper are ceph, coda, exfat, jfs,
ntfs, ocfs2, overlayfs, and vboxsf.
Honestly, several of them look like they really could just iterate their
directories in shared mode and skip the wrapper entirely, but the point
of this change is to not change semantics or fix filesystems that
haven't been fixed in the last 7+ years, but to finally get rid of the
dual iterators.
