xfs: set buf types when converting extent formats
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. cc: <stable@vger.kernel.org> # 3.10 to current Tested-by: Jan Kara <jack@suse.cz> Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
