Yes.  Nothing in the libibmad or infiniband_diags source code calls the
sys_read_* functions.  It's only used by libibumad.  (Hmm... I take back what I
said about merging libibcommon with libibumad then.)

On Windows, libibumad uses libibverbs to obtain any information that it needs.
Because libibumad uses a Windows specific MAD layer interface, the libibumad
implementation does not share any code between Windows and Linux.  So, if the
sys_read_* calls were merged directly into libibumad on Linux and kept internal,
then all problems with sys_read_* go away.
