which need to be zeroed as well.
The MSCC PHY driver can actually be converted not to copy the encryption

Merge tag 'slab-for-6.1-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab fixes from Vlastimil Babka:
"Most are small fixups as described below.
The !CONFIG_TRACING fix is a bit bigger and would normally be done in
the next merge window as part of upcoming hardening changes. But we
realized it can make the kmalloc waste tracking introduced in this
window inaccurate, so decided to go with it now.
Summary:
- Remove !CONFIG_TRACING kmalloc() wrappers intended to save a
function call, due to incompatilibity with recently introduced
wasted space tracking and planned hardening changes.

DMA sync functions should use the same direction that was used by DMA
mapping. Use DMA_BIDIRECTIONAL for XDP_TX from regular RQ, which reuses
the same mapping that was used for RX, and DMA_TO_DEVICE for XDP_TX from
XSK RQ and XDP_REDIRECT, which establish a new mapping in this
direction. On the RX side, use the same direction that was used when
setting up the mapping (DMA_BIDIRECTIONAL for XDP, DMA_FROM_DEVICE
otherwise).
Also don't skip sync for device when establishing a DMA_FROM_DEVICE
mapping for RX, as some architectures (ARM) may require invalidating
caches before the device can use the mapping. It doesn't break the
bugfix made in

never releases the CPU but calls down_trylock(&cmd→sem) in a busy loop.

Mlx5 LAG is initialized asynchronously on a workqueue which means that for
a brief moment after setting mlx5 UL representors as lower devices of a
bond netdevice the LAG itself is not fully initialized in the driver. When
adding such bond device to a bridge mlx5 bridge code will not consider it
as offload-capable, skip creating necessary bookkeeping and fail any
further bridge offload-related commands with it (setting VLANs, offloading
FDBs, etc.). In order to make the error explicit during bridge
initialization stage implement the code that detects such condition during
NETDEV_PRECHANGEUPPER event and returns an error.

Previously, the default number of transmit queues was 16. Due to
resource concerns, set to 8 queues instead. Still allow the user
to set more queues (max 16) if they like.
Since the driver is virtualized away from the physical NIC, the purpose
of multiple queues is purely to allow for parallel calls to the
hypervisor. Therefore, there is no noticeable effect on performance by
reducing queue count to 8.

The first patch is by Chen Zhongjin and adds a missing
dev_remove_pack() to the AF_CAN protocol.
Zhengchao Shao's patch fixes a potential NULL pointer deref in
AF_CAN's can_rx_register().
The next patch is by Oliver Hartkopp and targets the CAN ISO-TP
protocol, and fixes the state handling for echo TX processing.
Oliver Hartkopp's patch for the j1939 protocol adds a missing
initialization of the CAN headers inside outgoing skbs.
Another patch by Oliver Hartkopp fixes an out of bounds read in the
check for invalid CAN frames in the xmit callback of virtual CAN
devices. This touches all non virtual device drivers as we decided to
rename the function requiring that netdev_priv points to a struct
can_priv.
(Note: This patch will create a merge conflict with net-next where the
pch_can driver has removed.)
The last patch is by Geert Uytterhoeven and adds the missing ECC error
checks for the channels 2-7 in the rcar_canfd driver.
