Subject: ocfs2: allow for more than one data extent when creating xattr
Orabug: 18108070
ocfs2_xattr_extend_allocation() hits panic when creating xattr during data
extent alloc phase. The problem occurs if due to local alloc
fragmentation, clusters are spread over multiple extents. In this case
ocfs2_add_clusters_in_btree() finds no space to store more than one extent
record and therefore fails returning RESTART_META. The situation is
anticipated for xattr update case but not xattr create case. This fix
simply ports that code to create case.
