Description:
- It is a read only file. While reading, it gives '1' if that
- device supports nowayout feature else, it gives '0'.
+ It is a read/write file. While reading, it gives '1'
+ if the device has the nowayout feature set, otherwise
+ it gives '0'. Writing a '1' to the file enables the
+ nowayout feature. Once set, the nowayout feature
+ cannot be disabled, so writing a '0' either has no
+ effect (if the feature was already disabled) or
+ results in a permission error.
