Subject: linux-next: manual merge of the trivial tree with the wireless tree
Hi Jiri,
Today's linux-next merge of the trivial tree got a conflict in
Documentation/rfkill.txt between commit
c6d660ce29295d344fcdc3654274b4a0aad1a9c8 ("rfkill: rewrite") from the
wireless tree and commit 9976d9daf91d146724ad9c336f74c60d2195c386
("trivial: Miscellaneous documentation typo fixes") from the trivial tree.
I just used the version from the wireless tree since it has been
basically rewritten there (except I applied the "transmiter" to
"transmitter" fix - see below). Maybe the part of the trivial tree patch
that affects this file should be dropped.

type: Name of the key type ("wlan", "bluetooth", etc).
state: Current state of the transmitter
0: RFKILL_STATE_SOFT_BLOCKED
- transmitter is forced off, but one can override it
- by a write to the state attribute;
+ transmitter is turned off by software
1: RFKILL_STATE_UNBLOCKED
- transmiter is (potentially) active
- transmitter is NOT forced off, and may operate if
- all other conditions for such operation are met

++ transmitter is (potentially) active
2: RFKILL_STATE_HARD_BLOCKED
transmitter is forced off by something outside of
- the driver's control. One cannot set a device to
- this state through writes to the state attribute;
- claim: 1: Userspace handles events, 0: Kernel handles events
-
-Both the "state" and "claim" entries are also writable. For the "state" entry
-this means that when 1 or 0 is written, the device rfkill state (if not yet in
-the requested state), will be will be toggled accordingly.
-
-For the "claim" entry writing 1 to it means that the kernel no longer handles
-key events even though RFKILL_INPUT input was enabled. When "claim" has been
-set to 0, userspace should make sure that it listens for the input events or
-check the sysfs "state" entry regularly to correctly perform the required tasks
-when the rkfill key is pressed.
-
-A note about input devices and EV_SW events:
-
-In order to know the current state of an input device switch (like
-SW_RFKILL_ALL), you will need to use an IOCTL. That information is not
-available through sysfs in a generic way at this time, and it is not available
-through the rfkill class AT ALL.
+ the driver's control.
+ claim: 0: Kernel handles events (currently always reads that value)
+
+rfkill devices also issue uevents (with an action of "change"), with the
+following environment variables set:
+
+RFKILL_NAME
+RFKILL_STATE
+RFKILL_TYPE
+
+The contents of these variables corresponds to the "name", "state" and
+"type" sysfs files explained above.
