You might be able to get away without a dirent cache, but the mdcache is also the handle cache.

What do you mean by “FSAL is in the main memory”? Is it a pure memory FSAL or does it have some kind of back end?

Subject: [NFS-Ganesha-Devel] disable inode & dirents cache

My FSAL is in the main memory.  Should I disable inode and dirents caching?

If so, what all I save in terms of memory and open FDs. I am not worried much about saving

open FDs but I do not want memory to get occupied without much benefit.

How do I disable inode and dirents?
