Commit b1529a41f777 "ocfs2: should reclaim the inode if '__ocfs2_mknod_locked' returns an error" tried to reclaim the claimed inode if __ocfs2_mknod_locked() fails later. But this introduce a race, the freed bit may be reused immediately by another thread, which will update dinode, e.g. i_generation. Then iput this inode will lead to BUG: inode->i_generation != le32_to_cpu(fe->i_generation) We could make this inode as bad, but we did want to do operations like wipe in some cases. Since the claimed inode bit can only affect that an dinode is missing and will return back after fsck, it seems not a big problem. So just leave it as is by revert the reclaim logic.
