NFS: Fix a few further cache consistency regressions
Steve Dickson writes:
Doing the following:
1. On server:
$ mkdir ~/t
$ echo Hello > ~/t/tmp
2. On client, wait for a string to appear in this file:
$ until grep -q foo t/tmp ; do echo -n . ; sleep 1 ; done
3. On server, create a *new* file with the same name containing that
string:
$ mv ~/t/tmp ~/t/tmp.old; echo foo > ~/t/tmp
will show how the client will never (and I mean never ;-) ) see
the updated file.
The problem is that we do not update nfsi->cache_change_attribute when the
file changes on the server (we only update it when our client makes the
changes). This again means that functions like nfs_check_verifier() will
fail to register when the parent directory has changed and should trigger
a dentry lookup revalidation.
