=============
- `CONFIG_KALLSYMS_ALL`: state dump of mapping between block device
number and name
+### LTTng specific kernel config options
+
+The following kernel configuration options are provided by LTTng:
+
+ - `CONFIG_LTTNG`: Build LTTng (Defaults to 'm').
+ - `CONFIG_LTTNG_EXPERIMENTAL_BITWISE_ENUM`: Enable the experimental bitwise
+ enumerations (Defaults to 'n'). This can be enabled by building with:
+
+ make CONFIG_LTTNG_EXPERIMENTAL_BITWISE_ENUM=y
+
+ - `CONFIG_LTTNG_CLOCK_PLUGIN_TEST`: Build the test clock plugin (Defaults to
+ 'm'). This plugin overrides the trace clock and should always be built as a
+ module for testing.

add-context. Therefore, it is normal that the same counters attached to both the
stream context and event context show different values for a given event; what
matters is that they increment at the same rate.

+Supported versions
+------------------
+
+The LTTng project supports the last two released stable versions
+(e.g. stable-2.13 and stable-2.12).

+compatibility.
+
+Security fixes are backported from the master branch to both of the last stable
+version and the the second-last stable version.
+
+New kernel version enablement commits are integrated into the master branch and
