Re: [Linux-cluster] Synchronous Locking Function for Kernel



Hi,
I'm trying to use the DLM independently to acquire locks in the ext2 code. I'm calling the functions that refresh the kernel data structures in the AST after taking the locks. I'd like to know how to find out when this AST has been called, ie when do I know the final result of the locking so as to proceed in the ext2 function. I can see a completion structure in the holder structure in the glock layer. Is that what performs this task in the gfs?
Thanks
Renuka.
