[PATCH 0/3] sysrq: Simple fixes and console visibility

[Petr Mladek]

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
