Additional Comment #10 From Olaf Kirch 2003-09-16 21:13
The way I understood it the code is supposed to work like
umount(8) calls umount(2) with MNT_FORCE
umount(2) calls NFS to signal all RPC tasks
later notices there are still buys inodes and returns to
user space (-EBUSY)
umount(8) retries umount(2) call
If that assumption is incorrect, we indeed to wait for the rpc tasks to
complete. Nasty :-(
