Hi,

Now inode_table_t:lock is type of mutex which I think we can use
‘pthread_rwlock' to replace it for a better concurrency.

Because phread_rwlock allows more than one thread accessing inode table
at the same time.
Moreover, the critical section the lock is protecting won't take many
CPU cycles and no I/O and CPU fault/exception involved after a quick
glance at glusterfs code.
I hope I didn't miss something.
If I would get an ACK from major glusterfs developer, I will try to do it.


You are right. I believe this is possible. No harm in trying this out.

Xavier, Raghavendra, Pranith, Nithya, do you think this is possible?

Regards,

 
Thanks.
