must rely on TCP's error correction to detect data corruption
in the data payload.
- noasyncreaddir
- Disable client's use its local cache to satisfy readdir
- requests. (This does not change correctness; the client uses
- cached metadata only when a lease or capability ensures it is
- valid.)
+ dcache
+ Use the dcache contents to perform negative lookups and
+ readdir when the client has the entire directory contents in
+ its cache. (This does not change correctness; the client uses
+ cached metadata only when a lease or capability ensures it is
+ valid.)
+
+ nodcache
+ Do not use the dcache as above. This avoids a significant amount of
+ complex code, sacrificing performance without affecting correctness,
+ and is useful for tracking down bugs.
+ noasyncreaddir
+ Do not use the dcache as above for readdir.
