Subject: [PATCH 1/3] enhanced lookup ESTALE error handling (v3)

Hi.

This is a patch to enhance ESTALE error handling during the
lookup process.  The error, ESTALE, can occur when out of data
dentries, stored in the dcache, is used to translate a pathname
component to a dentry.  When this occurs, the dentry which
contains the pointer to the inode which refers to the non-existent
file is dropped from the dcache and then the lookup process
started again.  Care is taken to ensure that forward process is
always being made.  If forward process is not detected, then the
lookup process is terminated and the error, ENOENT, is returned
to the caller.

    Thanx...

        ps
