[Gluster-devel] Adding one variable to inode structure

[Tahereh Fattahi]

Assume that one client wants to search it's directories for video files.
 I want use something that helps this client to search just directories
that have this kind of file.
like a extended attribute, but I want this attribute be set by server not
by client.
I dont know which xlator is suitable for this work.
