[PATCH 2/2] NFSv42: Don't force attribute revalidation of the copy offload source

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

When a copy offload is performed, we do not expect the source file to
change other than perhaps to see the atime be updated.
