Description
We think this is the cause of some ballooning caches in ceph-fuse and the MDS that have been reported. The VFS will happily keep much larger dentry counts than our cache limits if it's a large-memory machine, and we presently can't drop them if the VFS has them around.
We might be able to do this easily with the fuse_lowlevel_notify_inval_entry call?
