Subject: [PATCH 4/4] context_tracking: uninitialize static variables
Date: Sat, 1 Aug 2020 19:46:03 +0100 [thread overview]
Message-ID: <20200801184603.310769-5-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200801184603.310769-1-jbi.octave@gmail.com>
Checkpatch tool reports an error at a staic variable declaration
"ERROR: do not initialise statics to false"
This is due to the fact that this variable is stored in the buffer
In the .bss section, one can not set an initial value
Here we can trust the compiler to automatically set them to false.
The variable has since been uninitialized.
