a3d412d4b9 media: Revert "media: camss: Make use of V4L2_CAP_IO_MC"
This reverts commit c90f1178dc.

The assumption of "Each entry in formats[] table has unique mbus_code"
is valid for the RDI entities, but not for the PIX ones.

Reverting this patch and creating a new one which handles the PIX entities
correctly results in smaller and more straightforward patch than doing the
changes on top of the current version.

5e67276638 media: adv748x: Configure device when resuming from sleep
If the device is powered off (for example during system suspend to ram)
the devices loses its configuration, especially the slave i2c mappings
and other configuration set at probe time. This renders the device
unusable and the only way to recover is to unbind and rebind the device
to the driver to run the probe setup again.

Add an early resume callback that reinitializes the device and setup the
slave i2c address mappings and other probe time configuration.

3c39a16d30 media: cedrus: Add support for VP8 decoding
VP8 in Cedrus shares same engine as H264.

Note that it seems necessary to call bitstream parsing functions,
to parse frame header, otherwise decoded image is garbage. This is
contrary to what is driver supposed to do. However, values are not
really used, so this might be acceptable. It's possible that bitstream
parsing functions set some internal VPU state, which is later necessary
for proper decoding. Biggest suspect is "VP8 probs update" trigger.

a181616487 Input: Add "inhibited" property
Userspace might want to implement a policy to temporarily disregard input
from certain devices, including not treating them as wakeup sources.

An example use case is a laptop, whose keyboard can be folded under the
screen to create tablet-like experience. The user then must hold the laptop
in such a way that it is difficult to avoid pressing the keyboard keys. It
is therefore desirable to temporarily disregard input from the keyboard,
until it is folded back. This obviously is a policy which should be kept
out of the kernel, but the kernel must provide suitable means to implement
such a policy.

This patch adds a sysfs interface for exactly this purpose.

To implement the said interface it adds an "inhibited" property to struct
input_dev, and effectively creates four states a device can be in: closed
uninhibited, closed inhibited, open uninhibited, open inhibited. It also
defers calling driver's ->open() and ->close() to until they are actually
needed, e.g. it makes no sense to prepare the underlying device for
generating events (->open()) if the device is inhibited.

              uninhibit
closed      <------------ closed
uninhibited ------------> inhibited
      | ^     inhibit        | ^
 1st  | |               1st  | |
 open | |               open | |
      | |                    | |
      | | last               | | last
      | | close              | | close
      v |     uninhibit      v |
open        <------------ open
uninhibited ------------> inhibited

The top inhibit/uninhibit transition happens when users == 0.
The bottom inhibit/uninhibit transition happens when users > 0.
The left open/close transition happens when !inhibited.
The right open/close transition happens when inhibited.
Due to all transitions being serialized with dev->mutex, it is impossible
to have "diagonal" transitions between closed uninhibited and open
inhibited or between open uninhibited and closed inhibited.

No new callbacks are added to drivers, because their open() and close()
serve exactly the purpose to tell the driver to start/stop providing
events to the input core. Consequently, open() and close() - if provided
- are called in both inhibit and uninhibit paths.

493720a485 f2fs: fix to avoid REQ_TIME and CP_TIME collision
Lei Li reported a issue: if foreground operations are frequent, background
checkpoint may be always skipped due to below check, result in losing more
data after sudden power-cut.

f2fs_balance_fs_bg()
...
	if (!is_idle(sbi, REQ_TIME) &&
		(!excess_dirty_nats(sbi) && !excess_dirty_nodes(sbi)))
		return;

E.g:
cp_interval = 5 second
idle_interval = 2 second
foreground operation interval = 1 second (append 1 byte per second into file)

In such case, no matter when it calls f2fs_balance_fs_bg(), is_idle(, REQ_TIME)
returns false, result in skipping background checkpoint.

This patch changes as below to make trigger condition being more reasonable:
- trigger sync_fs() if dirty_{nats,nodes} and prefree segs exceeds threshold;
- skip triggering sync_fs() if there is any background inflight IO or there is

8769918bf0 f2fs: change to use rwsem for cp_mutex
Use rwsem to ensure serialization of the callers and to avoid

7ad08a58bf f2fs: Handle casefolding with Encryption
Expand f2fs's casefolding support to include encrypted directories.  To
index casefolded+encrypted directories, we use the SipHash of the
casefolded name, keyed by a key derived from the directory's fscrypt
master key.  This ensures that the dirhash doesn't leak information
about the plaintext filenames.

Encryption keys are unavailable during roll-forward recovery, so we
can't compute the dirhash when recovering a new dentry in an encrypted +
casefolded directory.  To avoid having to force a checkpoint when a new
file is fsync'ed, store the dirhash on-disk appended to i_name.

This patch incorporates work by Eric Biggers <ebiggers@google.com>
and Jaegeuk Kim <jaegeuk@kernel.org>.

bb9cd9106b fscrypt: Have filesystems handle their d_ops
This shifts the responsibility of setting up dentry operations from
fscrypt to the individual filesystems, allowing them to have their own
operations while still setting fscrypt's d_revalidate as appropriate.

Most filesystems can just use generic_set_encrypted_ci_d_ops, unless
they have their own specific dentry operations as well. That operation
will set the minimal d_ops required under the circumstances.

Since the fscrypt d_ops are set later on, we must set all d_ops there,
since we cannot adjust those later on. This should not result in any
change in behavior.

608af70351 libfs: Add generic function for setting dentry_ops
This adds a function to set dentry operations at lookup time that will
work for both encrypted filenames and casefolded filenames.

A filesystem that supports both features simultaneously can use this
function during lookup preparations to set up its dentry operations once
fscrypt no longer does that itself.

Currently the casefolding dentry operation are always set if the
filesystem defines an encoding because the features is toggleable on
empty directories. Unlike in the encryption case, the dentry operations
used come from the parent. Since we don't know what set of functions
we'll eventually need, and cannot change them later, we enable the
casefolding operations if the filesystem supports them at all.

By splitting out the various cases, we support as few dentry operations
as we can get away with, maximizing compatibility with overlayfs, which
will not function if a filesystem supports certain dentry_operations.

34178b1bc4 f2fs: fix compat F2FS_IOC_{MOVE,GARBAGE_COLLECT}_RANGE
Eric reported a ioctl bug in below link:

https://lore.kernel.org/linux-f2fs-devel/20201103032234.GB2875@sol.localdomain/

That said, on some 32-bit architectures, u64 has only 32-bit alignment,
notably i386 and x86_32, so that size of struct f2fs_gc_range compiled
in x86_32 is 20 bytes, however the size in x86_64 is 24 bytes, binary
compiled in x86_32 can not call F2FS_IOC_GARBAGE_COLLECT_RANGE successfully
due to mismatched value of ioctl command in between binary and f2fs
module, similarly, F2FS_IOC_MOVE_RANGE will fail too.

In this patch we introduce two ioctls for compatibility of above special
32-bit binary:
- F2FS_IOC32_GARBAGE_COLLECT_RANGE
- F2FS_IOC32_MOVE_RANGE
