Subject: [nfs-utils PATCH] nfs(5): Add new rdirplus functionality, clarify
|
|
|
|
The proposed kernel [patch][1] will modify the rdirplus mount option to
|
|
accept optional string values of "none" and "force". Update the man page
|
|
to reflect these changes and clarify the current client's behavior for the
|
|
default.
