In linux kernel since version 5.2 (release Date: 2019-07-07)  
POSIX Access Control Lists (ACLs) support additional access rights
for users and groups beyond the standard owner/group/world scheme,
and this option selects support for ACLs specifically for ntfs
NOTE: this is linux only feature. Windows will ignore these ACLs.

If you don't know what Access Control Lists are, say N.
