autofs4: translate pids to the right namespace for the daemon
The PID and the TGID of the process triggering the mount are sent to the
daemon. Currently the global pid values are sent (ones valid in the
initial pid namespace) but this is wrong if the autofs daemon itself is
not running in the initial pid namespace.
So send the pid values that are valid in the namespace of the autofs daemon.
The namespace to use is taken from the oz_pgrp pid pointer, which was set
at mount time to the mounting process' pid namespace.
If the pid translation fails (the triggering process is in an unrelated
pid namespace) then the automount fails with ENOENT.

autofs4: allow autofs to work outside the initial PID namespace
Enable autofs4 to work in a "container". oz_pgrp is converted from pid_t
to struct pid and this is stored at mount time based on the "pgrp=" option
or if the option is missing then the current pgrp.
The "pgrp=" option is interpreted in the PID namespace of the current
process. This option is flawed in that it doesn't carry the namespace
information, so it should be deprecated. AFAICS the autofs daemon always
sends the current pgrp, which is the default anyway.
The oz_pgrp is also set from the AUTOFS_DEV_IOCTL_SETPIPEFD_CMD ioctl.
This ioctl sets oz_pgrp to the current pgrp. It is not allowed to change
the pid namespace.
oz_pgrp is used mainly to determine whether the process traversing the
autofs mount tree is the autofs daemon itself or not. This function now
compares the pid pointers instead of the pid_t values.
One other use of oz_pgrp is in autofs4_show_options. There is shows the
virtual pid number (i.e. the one that is valid inside the PID namespace
of the calling process)
For debugging printk convert oz_pgrp to the value in the initial pid
namespace.

These CamelCase uses may be acceptable and should not generate these

So, change checkpatch to read all the .h files in include/... and look
for preexisting CamelCase #defines, typedefs and function prototypes.
Add these to the existing camelcase hash so that any uses in the patch or

There are currently ~3500 files in include/. It takes about 10 cpu

That's about 4x the time for a similar git grep.
This preseeding is only done once when using --strict and only when there

backlight: add CONFIG_PM_SLEEP to suspend/resume functions
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build
warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM
callbacks defined by SIMPLE_DEV_PM_OPS are only used when the
CONFIG_PM_SLEEP is enabled.

backlight: convert from legacy pm ops to dev_pm_ops
Convert drivers/video/backlight/class to use dev_pm_ops for power
management and remove Legacy PM ops hooks. With this change, backlight
class registers suspend/resume callbacks via class->pm (dev_pm_ops)
instead of Legacy class->suspend/resume. When __device_suspend() runs
call-backs, it will find class->pm ops for the backlight class.

The driver core clears the driver data to NULL after device_release or on
probe failure, since commit 0998d063100 ("device-core: Ensure drvdata =
NULL when no driver is bound"). Thus, it is not needed to manually clear
the device driver data to NULL.

MAINTAINERS: fix tape driver file mappings
The masks for the st and osst tape drivers in MAINTAINERS are too
broad and include unrelated files. Make the file list accurate so that
maintainers of these drivers aren't bothered with unrelated work.
