Rather than directly using o2dlm, dlmfs can now use the stackglue. This allows it to use userspace cluster stacks and fs/dlm. This commit forces o2cb for now. A latter commit will bump the protocol version and allow non-o2cb stacks. This is one big sed, really. LKM_xxMODE becomes DLM_LOCK_xx. LKM_flag becomes DLM_LKF_flag. We also learn to check that the LVB is valid before reading it. Any DLM can lose the contents of the LVB during a complicated recovery. userdlm should be checking this. Now it does. dlmfs will return 0 from read(2) if the LVB was invalid. Signed-off-by: Joel Becker <joel.becker@oracle.com> |
