Thanks for replying but consider this scenario. What Wrapfs code do is this user_request ---> vfs_request ---> wrapfs_request ---> actual_fs_request ---> storage Now consider this scenario in a network environment (client machine) user_request ---> vfs_request ---> wrapfs_request ---> Network ---> (server machine)actual_fs_request ---> storage The network here gets client requests and send them to server and vice versa. > > Good luck. > > Avishay Traeger > http://www.fsl.cs.sunysb.edu/~avishay/ > > __________________________________________________ Do You Yahoo!?
