[XFS] add a FMODE flag to make XFS invisible I/O less hacky
XFS has a mode called invisble I/O that doesn't update any of the timestamps. It's used for HSM-style applications and exposed through the nasty open by handle ioctl. Instead of doing directly assignment of file operations that set an internal flag for it add a new FMODE_NOCMTIME flag that we can check in the normal file operations. (addition of the generic VFS flag has been ACKed by Al as an interims solution) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
