[Ocfs2-tools-devel] [PATCH] Fix - fsck.ocfs2 attempts to clear dx_dir blocks

[Goldwyn Rodrigues]

If a directory has dx_dir blocks, fsck attempts to clear them in global bitmap.

Steps to reproduce:
Make filesystem with indexed-dirs feature enabled. Make a directory and create
a lot of files in it. Run fsck.ocfs2 -f on this filesystem.

This fix accounts for the dx_leaf nodes and avoids clearing in global bitmap.
The patch reuses the normal file extent functions, which includes code
for refcounting which might not be relevant in this situation.
