> 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. 
> Pavel Shilovsky (3):
> fcntl: Introduce new O_DENY* open flags for network filesystems
> CIFS: Add O_DENY* open flags support
> CIFS: Use NT_CREATE_ANDX command for forcemand mounts
