Jan Kara df5e622340 ext4: fix deadlock in ext4_symlink() in ENOSPC conditions ... ext4_symlink() cannot call __page_symlink() with transaction open. __page_symlink() calls ext4_write_begin() which can wait for transaction commit if we are running out of space thus causing a deadlock. Also error recovery in ext4_truncate_failed_write() does not count with the transaction being already started (although I'm not aware of any particular deadlock here). 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.
