The first two patches are simple bug fixes.
The last one is RFC to fix a bug report. It is not obvious why sysrq debug operations show only the sysrq header on the console. The filtering by console_loglevel makes some sense. The level can actually be set by sysrq.
The solution implemented in the RFC is a warning. It is a simple idea but the implementation is relatively complicated. Mainly because all parts sysrq, printk, and consoles are heavily configurable.
PS: I sent the first patch also separately. It was simple and it was independent in my first draft of the RFC. I am sorry for confusion.
Petr Mladek (3): sysrq: Restore original console_loglevel when sysrq disabled sysrq: Remove duplicated sysrq message sysrq: Warn about insufficient console_loglevel
