ext3_symlink() cannot call __page_symlink() with transaction open. __page_symlink() calls ext3_write_begin() which gets page lock which ranks above transaction start (thus lock ordering is violated) and and also ext3_write_begin() waits for a transaction commit when we run out of space which never happens if we hold transaction open. Fix the problem by stopping a transaction before calling __page_symlink() (we have to be careful and put inode to orphan list so that it gets deleted in case of crash) and starting another one after __page_symlink() returns for addition of symlink into a directory.
