This patch introduces a new kernel configuration option, CONFIG_VFS_AGE_VERIFICATION, which mandates that processes register a valid birth date using a new prctl call (PR_SET_BIRTHDATE) before being allowed to create files. This is in response to new regulations requiring age verification for digital content creation. If a process hasn't registered a birthdate or is under 18 years old, file creation will fail with a new error code, ETOOYOUNG.
The patch also adds a new error number, ETOOYOUNG (134), and includes safeguards against bypassing verification through execve(). It playfully rejects birthdates indicating an age over 150, acknowledging the lack of support for immortal entities.
