[PATCH] NFS: Only warn on unrecognized mount options

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To provide compatibility with automounters who use a common set of mount
options for all file systems, change the NFS in-kernel mount option parser
to ignore mount options it doesn't recognize.
