This enables the __ASSERT() macro in the kernel code. If an assertion

enabling this adds a significant footprint, it should only be enabled

This option is a free-form string that is passed to the compiler
|

when building all parts of a project (i.e. kernel, LKMs, and USAPs).
|
|
The compiler options specified by this string supplement the
|
|
pre-defined set of compiler supplied by the build system,
|
|
and can be used to change compiler optimization, warning and error
|
|
messages, and so on.
|
|
|
|
A given LKM or USAP can override this setting by means of the
|
|
OVERRIDE_COMPILER_OPT make variable in its Makefile.
