Both regressions caused that a reader buffer might not get filled as much as possible. - Restore non-documented behavior of printk() reader API and make it official. It did not fill the last byte of the provided buffer before 5.10. Two architectures, powerpc and um, used it to add the trailing '\0'. There might theoretically be more callers depending on this behavior in userspace. * tag 'printk-for-5.11-printk-rework-fixup' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk: fix buffer overflow potential for print_text() printk: fix kmsg_dump_get_buffer length calulations printk: ringbuffer: fix line counting
