Add a flag ([EXT4|FS]_DAX_FL) to preserve FS_XFLAG_DAX in the ext4
inode.
Set the flag to be user visible and changeable. Set the flag to be
inherited. Allow applications to change the flag at any time except if
it conflicts with the set of mutually exclusive flags (Currently VERITY,
ENCRYPT, JOURNAL_DATA).
Furthermore, restrict setting any of the exclusive flags if DAX is set.
While conceptually possible, we do not allow setting EXT4_DAX_FL while
at the same time clearing exclusion flags (or vice versa) for 2 reasons:
1) The DAX flag does not take effect immediately which
introduces quite a bit of complexity
2) There is no clear use case for being this flexible
Finally, on regular files, flag the inode to not be cached to facilitate
changing S_DAX on the next creation of the inode.

We add 'always', 'never', and 'inode' (default). '-o dax' continues to
operate the same which is equivalent to 'always'. This new
functionality is limited to ext4 only.
Specifically we introduce a 2nd DAX mount flag EXT4_MOUNT2_DAX_NEVER and set
it and EXT4_MOUNT_DAX_ALWAYS appropriately for the mode.
We also force EXT4_MOUNT2_DAX_NEVER if !CONFIG_FS_DAX.
Finally, EXT4_MOUNT2_DAX_INODE is used solely to detect if the user
specified that option for printing.

To prevent complications with in memory inodes we only set S_DAX on
inode load. FS_XFLAG_DAX can be changed at any time and S_DAX will
change after inode eviction and reload.
Add init bool to ext4_set_inode_flags() to indicate if the inode is
being newly initialized.
Assert that S_DAX is not set on an inode which is just being loaded.

S_DAX should only be enabled when the underlying block device supports
dax.
Cache the underlying support for DAX in the super block and modify
ext4_should_use_dax() to check for device support prior to the over
riding mount option.
While we are at it change the function to ext4_should_enable_dax() as
this better reflects the ask as well as matches xfs.

Verity and DAX are incompatible. Changing the DAX mode due to a verity
flag change is wrong without a corresponding address_space_operations

Make the 2 options mutually exclusive by returning an error if DAX was

Recent change in virtio_net_hdr_to_skb() broke some packetdrill tests.
When --mss=XXX option is set, packetdrill always provide gso_type & gso_size
for its inbound packets, regardless of packet size.
if (packet->tcp && packet->mss) {
if (packet->ipv4)
gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV4;
else
gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV6;
gso.gso_size = packet->mss;
}
Since many other programs could do the same, relax virtio_net_hdr_to_skb()
to no longer return an error, but instead ignore gso settings.
This keeps Willem intent to make sure no malicious packet could
reach gso stack.
Note that TCP stack has a special logic in tcp_set_skb_tso_segs()
to clear gso_size for small packets.

net: ks8851: Unify KS8851 SPI and MLL drivers
The KS8851SNL/SNLI and KS8851-16MLL/MLLI/MLLU are very much the same pieces
of silicon, except the former has an SPI interface, while the later has a
parallel bus interface. Thus far, Linux has two separate drivers for each
and they are diverging considerably.
This series unifies them into a single driver with small SPI and parallel
bus specific parts. The approach here is to first separate out the SPI
specific parts into a separate file, then add parallel bus accessors in
another separate file and then finally remove the old parallel bus driver.
The reason for replacing the old parallel bus driver is because the SPI
bus driver is much higher quality.
Note that I dropped "net: ks8851: Drop define debug and pr_fmt()" for now,
will send it separatelly later.

Implement accessors for KS8851-16MLL/MLLI/MLLU parallel bus variant of
the KS8851. This is based off the ks8851_mll.c , which is a driver for
exactly the same hardware, however the ks8851.c code is much higher
quality. Hence, this patch pulls out the relevant information from the
ks8851_mll.c on how to access the bus, but uses the common ks8851.c
code. To make this patch reviewable, instead of rewriting ks8851_mll.c,
ks8851_mll.c is removed in a separate subsequent patch.
