Type: Improvement
Resolution: Fixed
Priority: Minor

Affects Version/s: None
Labels:

- xattr

Rank (Obsolete):

The patch implements an extended attribute cache for
a Lustre client. It is organized as a write-through
cache: reads are performed from cache, updates are sent
synchronously to the MDS. An additional inode bit
is added to protect the cache.

The patch itself will be uploaded shortly.
