Check for ethtool_ops structures that are only stored in the ethtool_ops field of a net_device structure or passed as the second argument to netdev_set_default_ethtool_ops. These contexts are declared const, so ethtool_ops structures that have these properties can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct ethtool_ops i@p = { ... }; @ok1@ identifier r.i; struct net_device e; position p; @@ e.ethtool_ops = &i@p; @ok2@ identifier r.i; expression e; position p; @@ netdev_set_default_ethtool_ops(e, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct ethtool_ops i = { ... }; // </smpl> Suggested-by:

After a code cleanup, we get a harmless warning about a variable that is unused when CONFIG_FS_POSIX_ACL is disabled: drivers/staging/lustre/lustre/llite/xattr.c: In function 'll_xattr_get_common': drivers/staging/lustre/lustre/llite/xattr.c:312:24: error: unused variable 'lli' [-Werror=unused-variable] This puts the variable declaration into the same #ifdef.

Currently it is not possible to send LNet traffic between two nodes using infiniband hardware that have different page sizes for the case when RDMA fragments are used. When two nodes establish a connection they tell the other node the maximum number of RDMA fragments they support. The issue is that the units are pages, and 256 64K pages corresponds to 16MB of data, whereas a 4K page system is limited to messages with 1MB of data. The solution is to report over the wire the maximum number of fragments in 4K unites regardless of the native page size. The recipient then uses its native page size to translate into the maximum number of pages sized fragments it can send to the other node. Signed-off-by:

ll_find_alias is responsible for getting alias for inode which can be reused. Directories are assumed to have unique alias, where in case of non-directories there can be multiple aliases. In case of lustre there can be two type of aliases i.e. discon_alias and invalid_alias. Usage of discon_alias in case of non-directories may corrupt dcache and leads to kernel crash. Changes made to avoid use of discon_alias in case of non-directories. Seagate-bug-id: MRP-2739, MRP-3601 Signed-off-by:

The patch removes find_cbdata callbacks and clear_nlink from dentry_iput path, since this piece of code makes a few races possible. The test case reproduces one of the possible races described in LU-7925: 1) two hard links are created for the same file 2) the test calls stat(2) for link #1 3) in the middle of 2) the test opens and closes link #2 4) in the middle of 2) the test drops the ldlm locks and forces dentry reclaim via vm.drop_caches=2 5) in the middle of 2) ll_d_iput() clears i_nlink for the inode 6) the initial stat(2) continues and copies the wrong i_nlink value into st_nlink Signed-off-by:

Assertion was happened for open request when rq_replay is set to 1. ASSERTION(mod->mod_open_req->rq_replay == 0) But this situation is not fatal for client, and could happened when mdc_close() failed. The fix allow to free such requests. If mdc_close fail, MDS doesn`t receive close request from client. And in a worst case client would be evicted. The test recreates issue when mdc_close failed and client asserts: ASSERTION( mod->mod_open_req->rq_replay == 0 ) failed Signed-off-by:Alexander Boyko <alexander.boyko@seagate.com> Seagate-bug-id: MRP-3156 Reviewed-on: http://review.whamcloud.com/17495 Intel-bug-id: https://jira.hpdd.intel.com/browse/LU-5282Reviewed-by:

Merge tag 'iio-for-4.9a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-testing Jonathan writes: First round of new features, device support and cleanups for IIO in the 4.9 cycle. Device support * ak8974 - New driver and bindings for this 2009 vintage magnetometer (it was very popular back then!) * atlas-ph-sensor - ORP sensor support(I had to look up what one of these was) * cio-dac - New driver for Measurement Computing DAC boards * dmard06 - New driver for Domintech DMARDO6 accelerometer. Also vendor prefix. * dmard09 - New driver for Domintech DMARD09 accelerometer. * maxim-thermocouple - max6675 and max31855 new driver * mt6577 auxdac - new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this hardware. * ti-adc161s626 - new driver for this TI single channel differential ADC. * vcnl4000 - support vcnl4010 and vcnl4020 which are compatible for all features currently supported by this driver. New features * Core - Allow retrieving of underlying iio_dev from a callback buffer handle. This is needed to allow client drivers to perform operations such as configuring the trigger used. * hid-sensors - asynchronous resume support to avoid really long resume times. * kxcjk-1013 - add the mysterious KIOX000A ACPI id seen in the wild. * Tools - lsiio now enumerates processed as well as raw channels. Cleanup * ad7298 - use iio_device_claim_direct_mode and friends to simplify locking around mode switching and drop some boilerplate. * ad7793 - use iio_device_claim_direct_mode and friends to simplify locking around mode switching and drop some boilerplate. * ade7854 - checkpatch fixups (alignment of parameters) * atlas-ph-sensor - use iio_device_claim_direct_mode and friends to simplify locking around mode switching and drop some boilerplate. - Switch to REGCACHE_NONE as there are no useful register to cache. * bma180 - use iio_device_claim_direct_mode and friends to simplify locking around mode switching and drop some boilerplate. * hdc100x - Add mention of the HDC1000 and HDC1008 to the Kconfig help text. * isl29018 - Add driver specific prefixes to defines and function names. - Remove excessive logging. - Drop newlines which add nothing to readability. - General tidying up of comments. - Drop I2C_CLASS_HWMON as irrelevant to driver. * isl29028 - Add driver specific prefixes to defines, enums and function names. - Drop comma's from available attribute output as not ABI compliant. - Drop I2C_CLASS_HWMON as irrelevant to driver. * kxsd9 - devicetree bindings. * mag3110 - This one wasn't locking to protect against mode switches during raw_reads. Use the iio_claim_direct_mode function to fix this buglet. * maxim-theromcouple - Fix missing selects for triggered buffer support in Kconfig. * nau7802 - Use complete instead of complete_all as only one completion at a time. * sx9500 - Use complete instead of complete_all as only one completion at a time. * us5182d - Add a missing error code asignment instead of checking the result of an already checked statement. * vcnl4000 - Use BIT macro where appropriate. - Refactor return codes in read_raw callback. - Add some missing locking for concurrent accesses to the device.
