[PATCH] file-has-acl: use acl_extended_file_nofollow() if available

[Kamil Dudka]

Hello,

the attached patch allows ls(1) from coreutils to eliminate unnecessary calls 
of getxattr() and thus prevents it from triggerring unnecessary mounts while 
listing files.  The feature is enabled automatically whenever 
acl_extended_file_nofollow() is available at build-time.  See the following 
bug for more details:

Thanks in advance for considering the patch!

Kamil
