configname: CONFIG_KASAN_GENERIC

KASAN mode
└─>Generic mode
In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
Enables generic KASAN mode.
Supported in both GCC and Clang. With GCC it requires version 4.9.2
or later for basic support and version 5.0 or later for detection of
out-of-bounds accesses for stack and global variables and for inline
instrumentation mode (CONFIG_KASAN_INLINE). With Clang it requires
version 3.7.0 or later and it doesn't support detection of
out-of-bounds accesses for global variables yet.
This mode consumes about 1/8th of available memory at kernel start
and introduces an overhead of ~x1.5 for the rest of the allocations.
The performance slowdown is ~x3.
For better error detection enable CONFIG_STACKTRACE.
Currently CONFIG_KASAN_GENERIC doesn't work with CONFIG_DEBUG_SLAB
(the resulting kernel does not boot).
