When to Get Tested? Periodically to evaluate liver function; whenever you are at risk for liver injury; when you are taking medications that may affect your liver; when you have a liver disease; when you have symptoms associated with liver damage, such as jaundice.
An inode is a data structure on a filesystem on Linux and other Unix-like operating systems that stores all the information about a file except its name and its actual data. A data structure is a way of storing data so that it can be used efficiently.
The major and minor numbers are paired in a single data type that the driver uses to identify a particular device. The combined device number (the major and minor numbers concatenated together) resides in the field i_rdev of the inode structure, which we introduce later.
