const char* print_tainted

(

void

)

print_tainted - return a string to represent the kernel taint state.

'P' - Proprietary module has been loaded. 'F' - Module has been forcibly loaded. 'S' - SMP with CPUs not designed for SMP. 'R' - User forced a module unload. 'M' - System experienced a machine check exception. 'B' - System has hit bad_page. 'U' - Userspace-defined naughtiness. 'D' - Kernel has oopsed before 'A' - ACPI table overridden. 'W' - Taint on warning. 'C' - modules from drivers/staging are loaded. 'I' - Working around severe firmware bug. 'O' - Out-of-tree module has been loaded.

The string is overwritten by the next call to print_tainted().
