2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: "Theodore Ts'o" (cherry picked from commit 45a90bfd90c1215bf824c0f705b409723f52361b) Also make sure the buffer heads are marked clean before submitting bh for writing. The previous code was marking the buffer head dirty, which would have forced an unneeded write (and seek) to the journal for no good reason.
