Please add a CRS corelen module and detect whether it was evicted by this fsnotify issue.
Also for the process which is doing fsnotify (__fsnotify_update_child_dentry_flags), please try get the directory it is iterating, and how many dentry under that directory, and what percentage are negative.

Thanks for the comments @biger410 . Yes, crs eviction detector was meant to go to another commit, which I just created:)
