From: Jan Kara Fix a bug in list scanning that can cause us to skip the last buffer on the checkpoint list (and hence fail to do any progress under some rather unfavorable conditions). The problem is we first do jh=next_jh and then test } while (jh!=last_jh); Hence we skip the last buffer on the list (if it was not the only buffer on the list). As we already do jh=next_jh; in the beginning of the loop we are safe to just remove the assignment in the end. It can happen that 'jh' will be freed at the point we test jh != last_jh but that does not matter as we never *dereference* the pointer.
