Hi, I think commits ea3d7209ca01da209cda6f0dea8be9cc4b7a933b 17048e8a083fec7ad841d88ef0812707fbc7e39f 32ebffd3bbb4162da5ff88f9a35dd32d0a28ea70 011278485ecc3cd2a3954b5d4c73101d919bf1fa should be backported to stable kernels since they fix nasty data corruption races in ext4. They are in ext4 since punch hole support was introduced (which was before 3.0, I didn't care to track it further back).
