Lets try and get this in for 6.1. I think there should be time still.

Fix to allow space to be freed immediately on delete

When a file gets deleted on GFS2, if a node can't get an exclusive lock on the file's iopen glock, it punts on actually freeing up the space, because another node is using the file.  When it does this, it needs to drop the iopen glock from its cache so that the other node can get an exclusive lock on it. With this patch, gfs2_delete_inode() sets GL_NOCACHE before dropping the shared lock on the iopen glock in preparation for grabbing it in the exclusive state.  Since the node needs the glock in the exclusive state, dropping the shared lock from the cache doesn't slow down the case where no other nodes are using the file.
