We normally can't create a new directory with the case-insensitive
option already set - except when we're creating a snapshot.
And if casefolding is enabled filesystem wide, we should still set it
even though not strictly required, for consistency.

We have to be able to print superblock sections even if they fail to

It seems btree node scan picked up a partially overwritten btree node,
and corrected the "bset version older than sb version_min" error -
resulting in an invalid superblock with a bad version_min field.
Don't run this check at all when we're in btree node scan, and when we
do run it, do something saner if the bset version is totally crazy.

Multiple ioctl handlers individually use a lot of stack space, and clang chooses
to inline them into the bch2_fs_ioctl() function, blowing through the warning
limit:
fs/bcachefs/chardev.c:655:6: error: stack frame size (1032) exceeds limit (1024) in 'bch2_fs_ioctl' [-Werror,-Wframe-larger-than]
655 | long bch2_fs_ioctl(struct bch_fs *c, unsigned cmd, void __user *arg)
By marking the largest two of them as noinline_for_stack, no indidual code path
ends up using this much, which avoids the warning and reduces the possible
total stack usage in the ioctl handler.

fsck_err() can return a transaction restart if passed a transaction
object - this has always been true when it has to drop locks to prompt
for user input, but we're seeing this more now that we're logging the
error being corrected in the journal.
gc_accounting_done() doesn't call fsck_err() from an actual commit loop,
and it doesn't need to be holding btree locks when it calls fsck_err(),
so the easy fix here for the unhandled transaction restart is to just
not pass it the transaction object. We'll miss out on the fancy new
logging, but that's ok.

bch2_btree_lost_data() gets called on btree node read error, but the
error might be transient.
btree_node_scan is expensive, and there's no need to run it persistently
(marking it in the superblock as required to run) - check_topology
will run it if required, via bch2_get_scanned_nodes().
Running it non-persistently is fine, to avoid check_topology having to
rewind recovery to run it.

bch2_btree_increase_depth() was originally for disaster recovery, to get
some data back from the journal when a btree root was bad.
We don't need it for that purpose anymore; on bad btree root we'll
launch btree node scan and reconstruct all the interior nodes.
If there's a key in the journal for a depth that doesn't exists, and
it's not from check_topology/btree node scan, we should just ignore it.

The next patch will add logging of the specific error being corrected in
repair paths to the journal; this means __bch2_fsck_err() can return
transaction restarts in places that previously weren't expecting them.
check_topology() is old code that doesn't use btree iterators for btree
node locking - it'll have to be rewritten in the future to work online.

Specify the properties which are essential and which are not for the
Tegra I2C driver to function correctly. This was not added correctly when
the TXT binding was converted to yaml. All the existing DT nodes have
these properties already and hence this does not break the ABI.
dmas and dma-names which were specified as a must in the TXT binding
is now made optional since the driver can work in PIO mode if dmas are
missing.

The output interface has a 4->6 program attached at ingress.
We try to loop the multicast skb back to the sending socket.
Ingress BPF runs as part of netif_rx(), pushes a valid v6 hdr
and changes skb->protocol to v6. We enter ip6_rcv_core which
tries to use skb_dst(). But the dst is still an IPv4 one left
after IPv4 mcast output.
Clear the dst in all BPF helpers which change the protocol.
Try to preserve metadata dsts, those may carry non-routing
metadata.

When the link is up, either eth_proto_oper or ext_eth_proto_oper
typically reports the active link protocol, from which both speed
and number of lanes can be retrieved. However, in certain cases,
such as when a NIC is connected via a non-standard cable, the
firmware may not report the protocol.
In such scenarios, the speed can still be obtained from the
data_rate_oper field in PTYS register. Since data_rate_oper
provides only speed information and lacks lane details, it is
incorrect to derive the number of lanes from it.
This patch corrects the behavior by setting the number of lanes to
UNKNOWN instead of incorrectly using MAX_LANES when relying on
data_rate_oper.

Previously, a unique tunnel id was added for the matching on TC
non-zero chains, to support inner header rewrite with goto action.
Later, it was used to support VF tunnel offload for vxlan, then for
Geneve and GRE. To support VF tunnel, a temporary mlx5_flow_spec is
used to parse tunnel options. For Geneve, if there is TLV option, a
object is created, or refcnt is added if already exists. But the
temporary mlx5_flow_spec is directly freed after parsing, which causes
the leak because no information regarding the object is saved in
flow's mlx5_flow_spec, which is used to free the object when deleting
the flow.
To fix the leak, call mlx5_geneve_tlv_option_del() before free the
temporary spec if it has TLV object.

When using and existing adv_info instance for broadcast source it
needs to be updated to periodic first before it can be reused, also in
case the existing instance already have data hci_set_adv_instance_data
cannot be used directly since it would overwrite the existing data so
this reappend the original data after the Broadcast ID, if one was
generated.
Example:
bluetoothctl># Add PBP to EA so it can be later referenced as the BIS ID
bluetoothctl> advertise.service 0x1856 0x00 0x00
bluetoothctl> advertise on
...
< HCI Command: LE Set Extended Advertising Data (0x08|0x0037) plen 13
Handle: 0x01
Operation: Complete extended advertising data (0x03)
Fragment preference: Minimize fragmentation (0x01)
Data length: 0x09
Service Data: Public Broadcast Announcement (0x1856)
Data[2]: 0000
Flags: 0x06
LE General Discoverable Mode
BR/EDR Not Supported
...
bluetoothctl># Attempt to acquire Broadcast Source transport

The len parameter is considered optional so it can be NULL so it cannot
be used for skipping to next entry of EIR_SERVICE_DATA.

Convert the PMEM device tree binding from text to YAML. This will allow
device trees with pmem-region nodes to pass dtbs_check.
