FUSE: Adapt readdirplus to application usage patterns
Use the same adaptive readdirplus mechanism as NFS: http://permalink.gmane.org/gmane.linux.nfs/49299 If the user space implementation wants to disable readdirplus temporarily, it could just return ENOTSUPP. Then kernel will recall it with readdir. Signed-off-by: Feng Shuo <steve.shuo.feng@gmail.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
