Hi Hyunchul,

   Thanks for pointing this out. I agree that we should avoid the $LX 
prefix to prevent confusion or a future semantics collision with WSL.

   Would $LINUXFLAGS be an acceptable name for this private EA?

   If you agree, I'll update the code and documentation, rerun the 
relevant tests, including the Windows NTFS and CHKDSK compatibility 
tests with the new name, and submit the revised patches as v4.

   I look forward to your feedback.

Thanks,
Baolin.
