* include: provide linux/errno.hAhmad Fatoum2023-11-231-1/+1
| | | | | | | | | | | | | | | We don't have the historic baggage of having to support different errno definitions depending on architecture. We thus have only asm-generic/errno.h and include that from errno.h and elsewhere directly. Kernel code however includes <linux/errno.h>, so let's provide that file as well and define there the Linux-specific errno's and include <asm-generic/errno.h> for all other errnos.
