Network filesystems CIFS, SMB2.0, SMB3.0 and NFSv4 have such flags - this change can benefit cifs and nfs modules. While this change is ok for network filesystems, itsn't not targeted for local filesystems due security problems (e.g. when a user process can deny root to delete a file).
Share flags are used by Windows applications and WINE have to deal with them too. While WINE can process open share flags itself on local filesystems, it can't do it if a file stored on a network share and is used by several clients. This patchset makes it possible for CIFS/SMB2.0/SMB3.0.
