-// Functions to access/create device major and minor numbers matching the
-// encoding used by the Linux kernel and glibc.
-//
-// The information below is extracted and adapted from bits/sysmacros.h in the
-// glibc sources:
-//
-// dev_t in glibc is 64-bit, with 32-bit major and minor numbers. glibc's
-// 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 backward compatible
-// with legacy systems where dev_t is 16 bits wide, encoded as MMmm. It is also
-// backward compatible with the Linux kernel, which for some architectures uses
-// 32-bit dev_t, encoded as mmmM MMmm.
