tsutomu.owa@toshiba.co.jp 294e7e4587 DLM: fix conversion deadlock when DLM_LKF_NODLCKWT flag is set ... When the DLM_LKF_NODLCKWT flag was set, even if conversion deadlock was detected, the caller of can_be_granted() was unknown. We change the behavior of can_be_granted() and change it to detect conversion deadlock regardless of whether the DLM_LKF_NODLCKWT flag is set or not. And depending on whether the DLM_LKF_NODLCKWT flag is set or not, we change the behavior at the caller of can_be_granted(). This fix has no effect except when using DLM_LKF_NODLCKWT flag. Currently, ocfs2 uses the DLM_LKF_NODLCKWT flag and does not expect a cancel operation from conversion deadlock when calling dlm_lock(). ocfs2 is implemented to perform a cancel operation by requesting BASTs (callback).
