The request xid was used to make sure the ost object timestamps
being updated by the out of order setattr/punch/write requests
properly. However, this mechanism is broken by the multiple rcvd
slot feature, where we deferred the xid assignment from request
packing to request sending.
This patch moved back the xid assignment to request packing, and
the manner of finding lowest unreplied xid is changed from scan
sending & delay list to scan a unreplied requests list.
This patch also skipped packing the known replied XID in connect
and disconnect request, so that we can make sure the known replied
XID is increased only on both server & client side.

CDC-Only CEC devices are CEC devices that can only handle CDC messages,
all other messages are ignored.
Add a flag to signal that this is a CDC-Only device and act accordingly.
Also add helper functions to identify if a CEC device is configured as a
CDC-Only device, a second TV, a switch or a processor, since these variations
cannot be determined by the logical address alone.

The CEC_MSG_INITIATE_ARC message is special since it is the ONLY
CEC message that accepts two possible valid replies:
CEC_MSG_REPORT_ARC_INITIATED and CEC_MSG_REPORT_ARC_TERMINATED.
So if the transmitted message is CEC_MSG_INITIATE_ARC and the remote
side replied with CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED,
then a msg->reply value of CEC_MSG_REPORT_ARC_INITIATED or
CEC_MSG_REPORT_ARC_TERMINATED will match either reply.
I thought about either adding a second reply2 field, but that's ugly
for all other messages that have only one reply, and what if in the
future a new message is added that can have three replies?
Another option would be to add a cec_msg flag, but really, the combination
of CEC_MSG_REPORT_ARC_INITIATED and a reply value of one of the two
possible replies already functions as a flag.
Another advantage of this approach is that it is safe to re-use a
cec_msg struct. No need to zero a flags field or a reply2 field.
So since this really is an exception in the CEC specification, I
decided to implement it as an exception as well.

By default the CEC_MSG_USER_CONTROL_PRESSED/RELEASED messages
are passed on to the follower(s) only. If the new
CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag is set in the
flags field of struct cec_log_addrs then these messages are also
passed on to the remote control input subsystem and they will appear
as keystrokes.
This used to be the default behavior, but now you have to explicitly
enable it. This is done to force the caller to think about possible
security issues (e.g. if these messages are used to enter passwords).

normal mutex_lock_killable directly.
We could do the same for the down_interruptible_killable here, but
it's better to just remove the semaphores entirely from the driver,
which also takes care of that.

With gcc-7, I got a new warning for this driver:
wilc1000/linux_wlan.c: In function 'wilc_netdev_cleanup':
wilc1000/linux_wlan.c:1224:15: error: 'vif[1]' may be used uninitialized in this function [-Werror=maybe-uninitialized]
wilc1000/linux_wlan.c:1224:15: error: 'vif[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized]
A closer look at the function reveals that it's more complex than
it needs to be, given that based on how the device is created
we always get
netdev_priv(vif->ndev) == vif
Based on this assumption, I found a few other places in the same file
that can be simplified. That code appears to be a relic from times
when the assumption above was not valid.

Commit 0557344e21 ("staging: comedi: ni_mio_common: fix local var for
32-bit read") changed the type of local variable `d` from `unsigned
short` to `unsigned int` to fix a bug introduced in
commit 9c340ac934 ("staging: comedi: ni_stc.h: add read/write
callbacks to struct ni_private") when reading AI data for NI PCI-6110
and PCI-6111 cards. Unfortunately, other parts of the function rely on
the variable being `unsigned short` when an offset value in local
variable `signbits` is added to `d` before writing the value to the
`data` array:
d += signbits;
data[n] = d;
The `signbits` variable will be non-zero in bipolar mode, and is used to
convert the hardware's 2's complement, 16-bit numbers to Comedi's
straight binary sample format (with 0 representing the most negative
voltage). This breaks because `d` is now 32 bits wide instead of 16
bits wide, so after the addition of `signbits`, `data[n]` ends up being
set to values above 65536 for negative voltages. This affects all
supported "E series" cards except PCI-6143 (and PXI-6143). Fix it by
ANDing the value written to the `data[n]` with the mask 0xffff.

For NI M Series cards, the Comedi `insn_read` handler for the AI

This patch is the main client part of a new feature that supports
multiple modify metadata RPCs in parallel. Its goal is to improve
metadata operations performance of a single client, while maintening
the consistency of MDT reply reconstruction and MDT recovery
mechanisms.
It allows to manage the number of modify RPCs in flight within
the client obd structure and to assign a virtual index (the tag) to
each modify RPC to help server side cleaning of reply data.
The mdc component uses this feature to send multiple modify RPCs
in parallel.

Implement non-blocking migration based on exclusive open instead of
group lock. Implemented exclusive close operation to atomically put
a lease, swap two layouts and close a file. This allows race-free
migrations.
Make the caller responsible for retrying on failure (EBUSY, EAGAIN)
in non-blocking mode.
In blocking mode, allow applications to trigger layout swaps using a
grouplock they already own, to prevent race conditions between the
actual data copy and the layout swap. Updated lfs accordingly. File
leases are also taken in blocking mode, so that lfs migrate can issue
a warning if an application attempts to open a file that is being
migrated and gets blocked.
Timestamps (atime/mtime) are set from userland, after the layout swap
is performed, to prevent conflicts with the grouplock.
lli_trunc_sem is taken/released in the vvp_io layer, under the DLM
lock. This re-ordering fixes the original issue between truncate and
migrate.

ptlrpc is using rq_xid as matchbits of bulk data, which means it
has to change rq_xid for bulk resend to avoid several bulk data
landing into the same buffer from different resends.
This patch uses one of reserved __u64 of ptlrpc_body to transfer
mbits to peer, matchbits is now separated from xid. With this change,
ptlrpc can keep rq_xid unchanged on resend, it only updates matchbits
for bulk data.
This protocol change is only applied if both sides of connection have
OBD_CONNECT_BULK_MBITS, otherwise, ptlrpc still uses old approach and

If you create a file, archive and release it, it keeps only a

with --xattr you will store the same striping information and link
information in the tar. If you delete the file, the file and archive
state does not make sense. Now if you restore the file using tar
with xattr having the RELEASED flag turned on, then it is not correct
because this is a new file. Hence ignoring the HSM xattr and masking
out the "RELEASED" flag for the files, which are not archived.

Do not lookup master inode by ilookup5, instead it should
use ilookup5_nowait, otherwise it will cause dead lock,
1. Client1 send chmod req to the MDT0, then on MDT0, it
enqueues master and all of its slaves lock, (mdt_attr_set()
->mdt_lock_slaves()), after gets master and stripe0 lock,
it will send the enqueue request(for stripe1) to MDT1, then
MDT1 finds the lock has been granted to client2. Then MDT1
sends blocking ast to client2.
2. At the same time, client2 tries to unlink the striped
dir (rm -rf striped_dir), and during lookup, it will hold
the master inode of the striped directory, whose inode state
is NEW, then tries to revalidate all of its slaves,
(ll_prep_inode()->ll_iget()->ll_read_inode2()->
ll_update_inode().). And it will be blocked on the server
side because of 1.
3. Then the client get the blocking_ast request, cancel the
lock, but being blocked by ilookup5 in ll_md_blocking_ast(),
because the inode state is still NEW.

This broke when I converted the 32-bit get_seconds() into
ktime_get_{real_,}seconds() inconsistently. Either
one of those two would have worked, but mixing them
does not.
Staying with the original intention of the patch, this
changes the ktime_get_seconds() calls into ktime_get_real_seconds(),
using real time instead of mononic time.

sysfs attribute is only checked to see if an error was returned.
This patch changes tsl2583_als_calibrate() to return 0 on success.

The check for ch1lux > ch0lux inside tsl2583_get_lux is only valid if
the ratio is not equal to zero. Move the code block inside the else
statement. This does away with the need to initialize the variables to
zero.

If channel 0 does not have any data, then the code sets the lux to zero.
The corresponding comment says that the last value is returned. This
updates the comment to correctly reflect what the code does. It also
clarifies the comment about why 0 is returned.

The definition of the tsl2583_device_lux struct has a series of single
line comments. There are two other cases where the multiline comments
did not have an initial blank line. Change these comments to use the
proper multiline syntax.

There are two separate files describing the tsl2583 sysfs attributes.
Combine the two files into one. Updated the name of the sysfs attributes
to match the current ABI.
