| Message-ID | <q8VbQ-1dV-3@gated-at.bofh.it> |
Applications use fsync/fdatasync to make sure data is written back to storage. It is expected that those system calls return error if writeback has failed (e.g. disk/transport failure, memory failure..) However if admins run a command such as sync or fsfreeze along side, fsync/fdatasync may return success even if writeback has failed. That could lead to data corruption. This patch is a minimal fix for the problem. -- Jun'ichi Nomura, NEC Corporation-- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
