gfs2: gfs2_walk_metadata fix
commit a27a0c9b6a208722016c8ec5ad31ec96082b91ec upstream.
It turns out that the current version of gfs2_metadata_walker suffers
from multiple problems that can cause gfs2_hole_size to report an
incorrect size. This will confuse fiemap as well as lseek with the
SEEK_DATA flag.
Fix that by changing gfs2_hole_walker to compute the metapath to the
first data block after the hole (if any), and compute the hole size
based on that.
Fixes xfstest generic/490.
