We use UniqueId to ensure that the root directory did not change UniqueId itself rather than using the UniqueId from the server. when the 'noserverino' mount option is used, the client generates
when you copy the second time, it should be read from the local cache (youĬould unmount and remount to reduce the page cache impact). try copying a huge file (say few hundred MBs) from mount point to localįilesystem (during the first time, the cache will be initialized) mount -t cifs //server/share -o user=guest dropped the patch to guard cifsglob.h against multiple inclusion as it CreateTime could be considered once some of related development we now check LastWriteTime, LastChangeTime and eof of server for dataĬoherency.
