Merge tag 'iio-for-4.9c' of git://git./linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Third set of new device support, functionality and cleanups for IIO in the 4.9 cycle.
Given Linus is hinting (strongly!) at an rc8 this last set is hopefully in
time for the 4.9 merge window. The zpa2326 and si1145 drivers provide
fine illustrations that devices aren't getting any simpler!
I'm also particularly pleased Linus Walliej did such a thorough job of cleaning
up one of my old drivers.
New device support
* mCube MC3230 accelerometer
- new fairly minimal driver.
* Murata zpa2326
- extensive new driver supporting the rather 'novel' buffering of data this
device provides and handling both it's own data ready trigger and other
triggers rather elegantly.
* si1141, si1142, si1143, si1145, si1146 and si1147 proximity, UV, visible and
IR sensors.
- another extensive new driver supporting all the key bits of what this
set of devices supplies including dataready triggers, buffers and all the
various data channels.
Functionality
* kxsd9 - Linus brought this scratch driver I wrote in one afternoon years ago
up to date adding lots of good stuff along the way.
- SPI support after extensive rework of the driver.
- Triggered buffer capture support.
- Runtime PM.
- Regulator handling.
- Mounting matrix support.
* mma7660
- Add MODULE_DEVICE_TABLE to support autoprobing.
Cleanups
* ad5933
- Align some function arguements nicely.
* med_z188
- Constify iio_info structure.
* sca3000
- Implement IIO_CHAN_INFO_SAMP_FREQ rather than a hand rolled attr.
There are still quite a few drivers that would benefit from similar updates.
* ssp_sensors
- Constify iio_info structures in accel and gyro drivers.

staging: lustre: mdc: cl_default_mds_easize not refreshed
The client_obd::cl_default_mds_easize field should track the largest
observed EA size advertised by the MDT, subject to a reasonable upper
bound. The MDC uses cl_default_mds_easize to calculate the initial
size of request buffers. The default value should be small enough to
avoid wasted memory and excessive use of vmalloc(), yet large enough
to accommodate the common use case.
In the current code, the default value is only updated if
client_obd::cl_max_mds_easize is strictly less than
mdt_body::mbo_max_mdsize. This condition is almost never met, because
client_obd::cl_max_mds_easize is computed at client mount-time based
on the number of OSTs in the filesystem, so the MDT won't ever observe
and advertise an EA size larger than that.
As a result, client_obd::cl_default_mds_easize indefinitely retains
its initial value, which is computed at client mount-time based on
the filesystem's default stripe width. Any getattr() requests for
widely striped files will consequently allocate a request buffer
that is too small, forcing reallocations on both the client and
server side. To avoid this, update client_obd::cl_default_mds_easize
independently of the value of client_obd::cl_max_mds_easize.
In addition, this patch includes these changes:
- Add comments to the client_obd structure to clarify what the
cl_{default,max}_mds_{cookie,ea}size values mean.
- Prevent mdc_get_info() from storing uninitialized data in
client_obd::cl_max_mds_cookiesize.
- Use 4096 as an upper bound for the default values. The former
bound of PAGE_CACHE_SIZE is too large on 64k-page platforms
(i.e. PPC), so it fails to prevent the vmalloc() spinlock
contention described in LU-3338. The new value was chosen to
be large enough to accommodate common use cases while staying
well below the 16k threshold at which allocations start using
vmalloc().

staging: lustre: ptlrpc: prevent request timeout grow due to recovery
Patch fixes the issue seen on the client with growing request
timeout which occurred after the server side patch landed for
LU-5079. While commit itself is correct, it reveals another
issue. If request is being processed for a long time on server
then client adaptive timeouts will adapt to that after receiving
reply and new requests will have bigger timeout. Another problem
is that server AT history is corrupted by recovery request
processing time which not pure service time but includes
also waiting time for clients to recover.
Patch prevents the AT stats update from early replies on client and
from recovering requests processing time on server.
The ptlrpc_at_recv_early_reply() still updates the current request
timeout as asked by server, but don't include this into AT stats.
The real reply will bring that data from server after all.

staging: lustre: obd: use proper flags for call_usermodehelper
When a parameter is permanently changed on the MGS the
MGS send a changelog packet to the proper nodes that
are affected by the change. Once the nodes receive the
change they then call the userland utility lctl to
change its local value. When calling a userland
application from the kernel you specify a flag to
control the interaction with the application. Originally
by default the flag was set to 0 which is UMH_NO_WAIT
which meant lctl was being called asynchronously. In
older kernels this was fine since UHM_NO_WAIT and
UHM_WAIT_PROC had nearly the same logic. This changed
with newer kernels which broke updating our parameters.
Plus doing a UHM_NO_WAIT doesn't report back a error
if something goes wrong with lctl. The fix is to set
the flag to UHM_WAIT_PROC so kernel space waits until
lctl has finished and we get a proper error code if
something does go wrong with lctl.

staging: lustre: llite: pack suppgid to MDS correctly
The ll_lookup_it() may trigger IT_OPEN RPC to open a file by name.
But at that time, the client does not know the target file's GID,
so it cannot pack the necessary supplementary group ID in the RPC.
Because of missing the supplementary group ID, the RPC maybe fail
for open permission check on the MDS. Under such case, MDS should
return the target file's GID, if the current thread on the client
in the right group (according to the file's GID), the client will
try the IT_OPEN RPC again with the right supplementary group ID.
This patch is also helpful if some other(s) changed the file's GID
after current RPC sent to the MDS with the suppgid as the original
GID by race.
