Hi.
The patch enhanced the ESTALE error handling for NFS mounted
file systems. It expands the number of places that the NFS
client checks for ESTALE returns from the server.
It also enhances the ESTALE handling for directories by
occasionally retrying revalidation to check to see whether the
directory becomes valid again. This sounds odd, but can occur
when a systems administrator, accidently or unknowingly,
unexports a file system which is in use. All active
non-directory files become permanently inaccessible, but
directories can be become accessible again after the
administrator re-exports the file system. This is a situation
that users have been complaining about for years and this
support can help to alleviate their situations.
As far as I can see, this patch can be applied separately from the VFS
fixes. If so, would it make sense for me to take charge of this patch in
the NFS tree, while Andrew queues up the other two VFS changes in -mm?
Yes, I think that this would make good sense.
Thanx...
