/* dev_t in glibc is a 64-bit quantity, with 32-bit major and minor numbers.
Our default encoding is MMMM Mmmm mmmM MMmm, where M is a hex digit of
the major number and m is a hex digit of the minor number. This is
downward compatible with legacy systems where dev_t is 16 bits wide,
encoded as MMmm. It is also downward compatible with the Linux kernel,
which (as of 2016) uses 32-bit dev_t, encoded as mmmM MMmm.
Systems that use an incompatible encoding for dev_t should override this
file in the appropriate sysdeps subdirectory. */
