Hi,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 Thomas Zimmermann (2): console: Replace #if 0 with atomic var 'ignore_console_lock_warning' fbdev/core: Disable console-lock warnings when fb.lockless_register_fb is set
I just saw this version after my comment on v2 that the race there was not really a problem. This version is even better though :) : Acked-by: Hans de Goede <hdego...@redhat.com> Regards, Hans _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
