[Nfs-ganesha-devel] Re: Question about operations between SAL <-> FSAL for locking

I set fso_lock_support_async_block = true, does it mean that disables the fact that SAL does not keep track of the lock itself and does not check blocked lock anymore? The lock_op2() returns ERR_FSAL_NO_ERROR if success, ERR_FSAL_LOCKED if the lock is already locked by another but for the moment I do not make any upcall at all. I have a test with blocking lock and it works, and I'm wondering & trying to figure out if the upcall is necessary. Do you have some advice? Thank you
