2008-10-23[CIFS] improve setlease handlingSteve French
fcntl(F_SETLEASE) currently is not exported by cifs (nor by local file systems) so cifs grants leases based on how other local processes have opened the file not by whether the file is cacheable (oplocked). This adds the check to make sure that the file is cacheable on the client before checking whether we can grant the lease locally (generic_setlease). It also adds a mount option for cifs (locallease) if the user wants to override this and try to grant leases even if the server did not grant oplock. Signed-off-by: Steve French <sfrench@us.ibm.com>

2008-10-23drm: Add 32-bit compatibility for DRM_IOCTL_UPDATE_DRAW.Eric Anholt

2008-10-23drm/i915: use pipes, not planes to label vblank dataKeith Packard
vblank in the kernel is far simpler if it deals with pipes instead of planes, so we're changing both user and kernel side. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-10-23drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operationsKeith Packard
To synchronize clip lists with the X server, the DRM lock must be held while looking at drawable clip lists. To synchronize with other ring access, the ring mutex must be held while inserting commands into the ring. Failure to do the first resulted in easy visual corruption when moving windows, and the second could have corrupted the ring with DRI2. Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the ring mutex means potentially sleeping. Deal with both of these by always running the tasklet from a work handler. Also, protect from clip list changes since the vblank request was queued by making sure the window has at least one rectangle while looking inside, preventing oopses .

2008-10-23i915: Enable IMR passthrough of vblank events before enabling it in pipestat.Eric Anholt
Otherwise, if we lost the race, the pipestat bit would be set without being reflected in IIR, and we would never clear the pipestat bit so the pipe event would never be generated again, and all vblank waits would time out.
