3.13.11-ckt18 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Dave Chinner <dchinner@xxxxxxxxxx> commit fe22d552b82d7cc7de1851233ae8bef579198637 upstream. Conversion from local to extent format does not set the buffer type correctly on the new extent buffer when a symlink data is moved out of line. Fix the symlink code and leave a comment in the generic bmap code reminding us that the format-specific data copy needs to set the destination buffer type appropriately.
