This reverts commit 86b20af11e84c26ae3fde4dcc4f490948e3f8035.
This patch leads to passing 0 to simple_read_from_buffer()
as a fifth argument, turning the read method into a nop.
The change is fundamentally flawed, as it breaks the driver.

SolidRun CN9130 SoM actually uses CP_MPP[0:1] for mdio. CP_MPP[40]
provides reference clock for dsa switch and ethernet phy on Clearfog
Pro, wheras MPP[41] controls efuse programming voltage "VHV".
Update the cp0 mdio pinctrl node to specify mpp0, mpp1.

The background blockgc scanner runs on a 5m interval by default and
trims preallocation (post-eof and cow fork) from inodes that are
otherwise idle. Idle effectively means that iolock can be acquired
without blocking and that the inode has no dirty pagecache or I/O in
flight.
This simple mechanism and heuristic has worked fairly well for
post-eof speculative preallocations. Support for reflink and COW
fork preallocations came sometime later and plugged into the same
mechanism, with similar heuristics. Some recent testing has shown
that COW fork preallocation may be notably more sensitive to blockgc
processing than post-eof preallocation, however.
For example, consider an 8GB reflinked file with a COW extent size
hint of 1MB. A worst case fully randomized overwrite of this file
results in ~8k extents of an average size of ~1MB. If the same
workload is interrupted a couple times for blockgc processing
(assuming the file goes idle), the resulting extent count explodes
to over 100k extents with an average size <100kB. This is
significantly worse than ideal and essentially defeats the COW
extent size hint mechanism.
While this particular test is instrumented, it reflects a fairly
reasonable pattern in practice where random I/Os might spread out
over a large period of time with varying periods of (in)activity.
For example, consider a cloned disk image file for a VM or container
with long uptime and variable and bursty usage. A background blockgc
scan that races and processes the image file when it happens to be
clean and idle can have a significant effect on the future
fragmentation level of the file, even when still in use.
To help combat this, update the heuristic to skip cowblocks inodes
that are currently opened for write access during non-sync blockgc
scans. This allows COW fork preallocations to persist for as long as
possible unless otherwise needed for functional purposes (i.e. a
sync scan), the file is idle and closed, or the inode is being
evicted from cache. While here, update the comments to help
distinguish performance oriented heuristics from the logic that
exists to maintain functional correctness.

Currently the debug-only xfs_bmap_exact_minlen_extent_alloc allocation
variant fails to drop into the lowmode last resort allocator, and
thus can sometimes fail allocations for which the caller has a
transaction block reservation.
Fix this by using xfs_bmap_btalloc_low_space to do the actual allocation.

Exact minlen allocations only exist as an error injection tool for debug
builds. Currently this is implemented using ifdefs, which means the code
isn't even compiled for non-XFS_DEBUG builds. Enhance the compile test
coverage by always building the code and use the compilers' dead code
elimination to remove it from the generated binary instead.
The only downside is that the alloc_minlen_only field is unconditionally
added to struct xfs_alloc_args now, but by moving it around and packing
it tightly this doesn't actually increase the size of the structure.

Just like xfs_attr3_leaf_split, xfs_attr_node_try_addname can return
-ENOSPC both for an actual failure to allocate a disk block, but also
to signal the caller to convert the format of the attr fork. Use magic
1 to ask for the conversion here as well.
Note that unlike the similar issue in xfs_attr3_leaf_split, this one was
only found by code review.

xfs_attr3_leaf_split propagates the need for an extra btree split as
-ENOSPC to it's only caller, but the same return value can also be
returned from xfs_da_grow_inode when it fails to find free space.
Distinguish the two cases by returning 1 for the extra split case instead
of overloading -ENOSPC.
This can be triggered relatively easily with the pending realtime group
support and a file system with a lot of small zones that use metadata
space on the main device. In this case every about 5-10th run of
xfs/538 runs into the following assert:
ASSERT(oldblk->magic == XFS_ATTR_LEAF_MAGIC);
in xfs_attr3_leaf_split caused by an allocation failure. Note that
the allocation failure is caused by another bug that will be fixed
subsequently, but this commit at least sorts out the error handling.

Use !try_cmpxchg instead of cmpxchg (*ptr, old, new) != old in
xlog_cil_insert_pcp_aggregate(). x86 CMPXCHG instruction returns
success in ZF flag, so this change saves a compare after cmpxchg.
Also, try_cmpxchg implicitly assigns old *ptr value to "old" when
cmpxchg fails. There is no need to re-read the value in the loop.
Note that the value from *ptr should be read using READ_ONCE to
prevent the compiler from merging, refetching or reordering the read.
No functional change intended.

Calling 'ln -s . symlink' or 'ln -s .. symlink' creates symlink pointing to
some object name which ends with U+F029 unicode codepoint. This is because
trailing dot in the object name is replaced by non-ASCII unicode codepoint.
So Linux SMB client currently is not able to create native symlink pointing
to current or parent directory on Windows SMB server which can be read by
either on local Windows server or by any other SMB client which does not
implement compatible-reverse character replacement.
Fix this problem in cifsConvertToUTF16() function which is doing that
character replacement. Function comment already says that it does not need
to handle special cases '.' and '..', but after introduction of native
symlinks in reparse point form, this handling is needed.
Note that this change depends on the previous change
"cifs: Improve creating native symlinks pointing to directory".

SMB protocol for native symlinks distinguish between symlink to directory
and symlink to file. These two symlink types cannot be exchanged, which
means that symlink of file type pointing to directory cannot be resolved at
all (and vice-versa).
Windows follows this rule for local filesystems (NTFS) and also for SMB.
Linux SMB client currenly creates all native symlinks of file type. Which
means that Windows (and some other SMB clients) cannot resolve symlinks
pointing to directory created by Linux SMB client.
As Linux system does not distinguish between directory and file symlinks,
its API does not provide enough information for Linux SMB client during
creating of native symlinks.
Add some heuristic into the Linux SMB client for choosing the correct
symlink type during symlink creation. Check if the symlink target location
ends with slash, or last path component is dot or dot-dot, and check if the
target location on SMB share exists and is a directory. If at least one
condition is truth then create a new SMB symlink of directory type.
Otherwise create it as file type symlink.
This change improves interoperability with Windows systems. Windows systems
would be able to resolve more SMB symlinks created by Linux SMB client
which points to existing directory.

The checking for whether or not io_uring can do a non-blocking read or
write attempt is gated on FMODE_NOWAIT. However, if the file is
pollable, it's feasible to just check if it's currently in a state in
which it can sanely receive or send _some_ data.
This avoids unnecessary io-wq punts, and repeated worthless retries
before doing that punt, by assuming that some data can get delivered
or received if poll tells us that is true. It also allows multishot
reads to properly work with these types of files, enabling a bit of
a cleanup of the logic that:
c9d952b9103b ("io_uring/rw: fix cflags posting for single issue multishot read")
had to put in place.

In the current implementation of the ltc2664_channel_config() function,
a variable named span is declared and initialized to 0, intended to
capture the return value of the ltc2664_set_span() function. However,
the output of ltc2664_set_span() is directly assigned to chan->span,
leaving span unchanged. As a result, when the function later checks
if (span < 0), this condition will never trigger an error since
span remains 0, this flaw leads to ineffective error handling. Resolve
this issue by using the ret variable to get the return value and later
assign it if successful and remove unused span variable.

If multishot gets disabled, and hence the request will get terminated
rather than persist for more iterations, then posting the CQE with the
right cflags is still important. Most notably, the buffer reference
needs to be included.
Refactor the return of __io_read() a bit, so that the provided buffer
is always put correctly, and hence returned to the application.

platform_device_register() errors
x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().
When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.
