Unfortunately no, you could look at what was done for uncached readdir in 2.4
and do something similar in 2.2 (would mean porting what was done in
FSAL_MDCACHE back to cache_inode). It’s actually probably not that horrible if
you wanted no dirent caching at all. Or you could keep dirent caching from
lookups etc while skipping dirent cache for readdir.

Thank you. Is there a way for FSAL to disable dirent caching in version 2.2?

Ok, I see how that can happen.
The 2.4 stable branch has something that should be a workaround, set
CacheInode {
Dir_Max = 1;
}
In your config which disables dirent caching, that might workaround.
In the meantime I am working on a new dirent cache that will use the cookies
from the underlying filesystem, and if it doesn’t find the start cookie in the
cache, it will do an underlying readdir starting at that cookie, which will
either find a next dirent, or will be beyond the end of the directory and
indicate end of dir. It will also preserve the dirent order from the
underlying filesystem so all of this will work.
I hope to finish that next week, and if all goes well, it is slated for
backport to 2.4 stable.

I am using
My application does the following..
1) opendir
2) readdir(entry) (exit loop if error)
3) delete(entry)
4) go to step 1
After deleting all entries in the directory it exits from step 2 with error
code 523 (BADCOOKIE).
I verified this application with NFSGanesha and with other NFS servers.
Only Ganesha (2.2.0-6.el7) returns this error.
Has this been fixed in a recent version. If yes which version has this fix?
Thank you
