+Description:
+ Enable passing additional variables for synthetic uevents that
+ are generated by writing /sys/.../uevent file.
+
+ Recognized extended format is ACTION [UUID [KEY=VALUE ...].
+
+ The ACTION is compulsory - it is the name of the uevent action
+ ("add", "change", "remove"). There is no change compared to
+ previous functionality here. The rest of the extended format
+ is optional.
+
+ You need to pass UUID first before any KEY=VALUE pairs.
+ The UUID must be in "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+ format where 'x' is a hex digit. The UUID is considered to be
+ a transaction identifier so it's possible to use the same UUID
+ value for one or more synthetic uevents in which case we
+ logically group these uevents together for any userspace
+ listeners. The UUID value appears in uevent as
+ "SYNTH_UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" environment
+ variable.
+
+ If UUID is not passed in, the generated synthetic uevent gains
+ "SYNTH_UUID=0" environment variable automatically.
+
+ The KEY=VALUE pairs can contain alphanumeric characters only.
+ It's possible to define zero or more pairs - each pair is then
+ delimited by a space character ' '. Each pair appears in
+ synthetic uevent as "SYNTH_ARG_KEY=VALUE". That means the KEY
+ name gains "SYNTH_ARG_" prefix to avoid possible collisions
+ with existing variables.
+
+ Example of valid sequence written to the uevent file:
+
+ add fe4d7c9d-b8c6-4a70-9ef1-3d8a58d18eed A=1 B=abc
+
+ This generates synthetic uevent including these variables:
+
+ ACTION=add
+ SYNTH_ARG_A=1
+ SYNTH_ARG_B=abc
