PATH NAME CACHE FOR NOTIFICATIONS OF FILE CHANGES

摘要

Change notify responses can be utilized to inform a remote computer that a file or directory that is being monitored has changed. A change notify response can include a path name to the file or directory being referenced. In some examples, a cache of path names can be maintained in a user space of a server implementing change notify responses. When a module that generates a change notify response does generate such a response, the module can first access the cache to determine if the relevant path name is located in the cache. Where the relevant path name is not located in the cache, the module can obtain the path name from kernel space and store it in the cache.
