staging: lustre: lnet: remove cfs_block_allsigs calls. · 2a4b6881

NeilBrown authored Feb 20, 2018

Both places that cfs_block_allsigs() is used here,
the goal is to turn an interruptible wait into an
uninterruptible way.
So instead of blocking the signals, change TASK_INTERRUPTIBLE to
TASK_NOLOAD.
In each case, no other functions called while signals are blocked
will sleep - just the one that has been fixed.
In one case, an extra 'interruptible' flag needs to be passed
down so the waiting decision can be made at the right place.

staging: lustre: remove unnecessary cfs_block_allsigs() calls · 1b2dad14

NeilBrown authored Feb 20, 2018

Threads started by kthread_run() ignore all signals,
as kthreadd() calls ignore_signals(), and this is
inherited by all children.
So there is no need to call cfs_block_allsigs() in functions
that are only run from kthread_run().

staging: lustre: remove linux-curproc.c · 37d3b407

NeilBrown authored Feb 20, 2018

The only functionality remaining here is
cfs_curproc_cap_pack(),
and it can be trivially implemented as an inline
in curproc.h.
So do that and remove the file.

staging: lustre: opencode cfs_cap_{raise, lower, raised} · cc738c1a

NeilBrown authored Feb 20, 2018

Each of these functions is used precisely once, so having
a separate exported function seems like overkill.

cfs_cap_raised() is trivial - one line.
cfs_cap_raise() and cfs_cap_lower() are used as a pair
which is more effectively implemented with
override_cred() / revert_creds().

staging: lustre: replace all CFS_CAP_* macros with CAP_* · 5ebaa2d1

NeilBrown authored Feb 20, 2018

Lustre defines a few CFS_CAP_* macros which are exactly the
same as the corresponding CAP_* macro, with one exception.

CFS_CAP_SYS_BOOT is 23
CAP_SYS_BOOT is 22.

CFS_CAP_SYS_BOOT is only used through CFS_CAP_FS_MASK and
causes capability 23 (CAP_SYS_NICE) to be dropped in certain
circumstances.
It is probable that the intention was to drop CAP_SYS_BOOT,
and this is what is now done.

CFS_CAP_CHOWN_MASK and CFS_CAP_SYS_RESOURCE_MASK are never
used, so they have been removed.

Jonathan writes:

First round of new devices, features and cleanups for IIO in the 4.17 cycle.

Outside of IIO
* Strongly typed 64bit int_sqrt function needed by the mlx90632

New device support
* adc081s
  - New driver supporting adc081s, adc101s and adc121s TI ADCs.
* ad5272
  - New driver supproting the ad5272 and ad5274 ADI digital potentiometers
    with DT bindings.
* axp20x_adc
  - support the AXP813 ADC - includes rework patches to prepare for this.
* mlx90632
  - New driver with dt bindings for this IR temperature sensor.

Features
* axp20x_adc
  - Add DT bindings and probing.
* dht11
  - The sensor has a wider range than advertised in the datasheet - support it.
* st_lsm6dsx
  - Add hardware timestamp su9pport.

Cleanups
* ABI docs
  - Update email contact for Matt Ranostay
* SPDX changes
  - Matt Ranostay has moved his drivers over to SPDX.  Currently we are making
    this an author choice in IIO.
* ad7192
  - Disable burnout current on misconfiguration.  No actually effect as
    they simply won't work otherwise.
* ad7476
  - Drop a license definition that was replicating information in SPDX tag.
* ade7758
  - Expand buf_lock to cover both buffer and state protection allowing
    unintented uses of mlock in the core to be removed.
* ade7759
  - Align parameters to opening parenthesis.
* at91_adc
  - Depend on sysfs instead of selecting it - for try wide consistency.
* ccs811
  - trivial naming type for a define.
* ep93xx
  - Drop a redundant return as a result checking platform_get_resource.
* hts221
  - Regmap conversion which simplifies the driver somewhat.
  - Clean up some restricted endian cast warnings.
  - Drop a trailing whitespace from a comment
  - Drop an unnecessary get_unaligned by changing to the right 16bit data type.
* ms5611
  - Fix coding style in the probe function (whitespace)
* st_accel
  - Use strlcpy instead of strncpy to avoid potentially truncating a string.
