Subject: [PATCH] nfs4_setfacl: add a specific option for indexes

nfs4_setfacl had the possibility to use an optional index
to add/remove an ACL entry.
This was causing some confusion as numeric files could be interpreted
as indexes.
This change adds an extra command line option '-i' to specifically
handle the indexes.
The index can be used only with certain operations (add and remove).
The new syntax, when using indexes, would be:

~]# nfs4_setfacl -i 3 -a A::101:rxtncy file123

Thanks Steve.
I wasn't sure this would be accepted, I'll send another patch for the man
page.

FYI... I'm going to wait for the man page before I

Sorry for the delay, I just sent a new version with a couple of fixes and
the man page.

Thanks,
