Convert array index from the loop bound to the loop index. The structure cl_env_percpu[NR_CPUS] has been initializing for each possible cpu (i.e 0 to i). During initialization if any error will occurred, the error handling code should uninitialize cl_env_percpu upto i. But currently unitialization is repeatedly done for the same cl_env_percpu[i] element. This does not seems to be correct. Used below semantic patch to identify this issue: @@ expression e1,e2,ar; @@ for(e1 = 0; e1 < e2; e1++) { <... ar[ - e2 + e1 ] ...> } Signed-off-by: -

Merge tag 'iio-for-4.9c' of git://git.kernel.org/pub/scm/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.

The previous patch, http://review.whamcloud.com/21304/, removed a check needed until LU-5718 is properly addressed. With the check, LU-5718 results in an error message and a lost RDMA operation. Without it, we have memory corruption and a crash (much harder to debug). Putting the check back in case LU-5718 is not fixed soon. Signed-off-by:

The code to allow peer_credits to be set per NI was originally "left inactive" because there were concerns about peer_credits interfering with the ability for IB nodes to connect to each other when peer_credits are not the same (peer_credits controls the queue depth for IB). With LU-3322, the values do not have to match so it is now safe to enable this code so peer_credits can be set per NI. This patch enables existing code for setting per NI peer_credits. Second this patch fixes a long standing bug in that the conf data was not being used to set variables in the lnet_ni structure until after lnd_startup() was called which meant LND drivers were ignoring struct lnet_ni tunable values being set. Now we change struct lnet_ni data fields based on conf data before calling lnd_startup(). Signed-off-by:

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().

Ned Bass authored
Allow default_easize to be tuned via /sysfs. A system administrator might want this if a rare access to widely striped files drives up the value on a filesystem where narrowly striped files are the more common case. In practice, however, this is wanted primarily to facilitate a test case for LU-5549. - Plumb the necessary interfaces through the LMV and MDC layers to expose write access to this value by higher layers. - Add block comments to modified functions.
