this is version 3 of the WARN_CONSOLE_UNLOCKED patch set. The macro prints a warning if the console's critical sections are entered without holding the console lock. This patch set allows to disable the warnings while debugging the console.
In the original approach, WARN_CONSOLE_UNLOCKED was disabled by setting ignore_console_lock_warning of type bool. As suggested by Petr Mladek, the new implementation is based on atomic_t and allows multiple threads to manipulate the warning state concurrently.
With version 3, the patch set now includes the patch for introducing ignore_console_lock_warning. This patch superseds all previous patches of the same purpose.
Best regards Thomas
v3:
- implement ignore_console_lock_warning with atomic_t
v2:
- restore ignore_console_lock_warning if lock_fb_info() fails
