A method of purging cached open files from a client-side delayed close list on
a remote file system. The remote file system stores a unique file identifier for
each cached open file which is independent of the cached file's namespace. In response
to a delete or rename command of a remote target file, the remote file system obtains
a target file identifier from the target file's server. The remote file system
then compares the target file identifier with each of the cached file's unique
file identifier. If a cached file's unique file identifier matches the target file
identifier, the cached file is purged from the delayed close list.
