Subject: xfs: set buf types when converting extent formats
From: Dave Chinner <[email protected]>
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.
