[PATCH] NFS: Do not flush the readdir cache in nfs_dentry_iput()

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

 



From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

The original premise in commit 83672d392f7b ("NFS: Fix directory caching
problem - with test case and patch.") was that readdirplus was caching
attribute information and replaying it later. This is no longer the
case.
