2d95ccf1a3 Start implementing verbose logging depends on macros. (SIMPLEFS_DEBUG) 
In many cases we don't need such verbose loggin, just add macros to
print loggin only if SIMPLEFS_DEBUG isset.
And it will be installed by default. (in Makefile)

18df3131a2 Don't change filp->f_pos in fops->iterate. (linux kernel >= 3.11) 
iterate_dir() already change filp->f_pos (using ctx->f_pos).
Thanks to Ivan.
