[PATCH] inotify/idr leak fix
Fix a bug which was reported and diagnosed by
Stefan Jones <stefan.jones@churchillrandoms.co.uk>
IDR trees include a cache of idr_layer objects. There's no way to destroy
this cache, so when we discard an overall idr tree we end up leaking some
memory.
Add and use idr_destroy() for this. v9fs and infiniband also need to use
idr_destroy() to avoid leaks.
Or, we make the cache global, like radix_tree_preload(). Which is probably
better. Later.
