From: Jeff Layton <jlay...@kernel.org> [ Upstream commit fb33c114d3ed5bdac230716f5b0a93b56b92a90d ]
It's possible for the VFS to completely forget about an inode, but for it to still be sitting on the cap release queue. If the MDS sends the client a cap message for such an inode, it just ignores it today, which can lead to a stall of up to 5s until the cap release queue is flushed. If we get a cap message for an inode that can't be located, then go ahead and flush the cap release queue.
