└─>Support symbolic error names in printf
In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
If you say Y here, the kernel's printf implementation will
be able to print symbolic error names such as ENOSPC instead
of the number 28. It makes the kernel image slightly larger
(about 3KB), but can make the kernel logs easier to read.
