    Description

      Auto PCC-RO attach during PCC open will try to change the layout to read-only state on MDT. If the intent open in atomic_open returns the lock with MDS_INODELOCK_LAYOUT bit set, it may cause dead lock. Thus it would better to release the intent lock first before call PCC open.
