So this bug is not over yet :(
I have checked my kernel source and indeed it have this patch but I still get the hang.
PS. my linux-2.6-2.6.30/fs/ocfs2/dcache.c kernel source has:
??? 290???????? else
??? 291???????????????? mlog_errno(ret);
??? 292
??? 293???????? /*
??? 294????????? * In case of error, manually free the allocation and do the iput().
??? 295????????? * We need to do this because error here means no d_instantiate(),
??? 296????????? * which means iput() will not be called during dput(dentry).
??? 297????????? */
??? 298???????? if (ret < 0 && !alias) {
??? 299???????????????? ocfs2_lock_res_free(&dl->dl_lockres);
??? 300???????????????? BUG_ON(dl->dl_count != 1);
??? 301???????????????? spin_lock(&dentry_attach_lock);
??? 302???????????????? dentry->d_fsdata = NULL;
??? 303???????????????? spin_unlock(&dentry_attach_lock);
??? 304???????????????? kfree(dl);
??? 305???????????????? iput(inode);
??? 306???????? }
??? 307
??? 308???????? dput(alias);
??? 309
??? 310???????? return ret;
??? 311 }

yes, 2.6.30 already have the fix for?

?
And yes, it is in the kernel. So your tools aren't affected.?
