2016-08-30NFSv4.x: Fix a refcount leak in nfs_callback_up_netTrond Myklebust

2016-08-30NFS4: Avoid migration loopsBenjamin Coddington
If a server returns itself as a location while migrating, the client may end up getting stuck attempting to migrate twice to the same server. Catch this by checking if the nfs_client found is the same as the existing client. For the other two callers to nfs4_set_client, the nfs_client will always be ERR_PTR(-EINVAL).

2016-08-30ARM: EXYNOS: Clear OF_POPULATED flag from PMU node in IRQ init callbackJavier Martinez Canillas
The Exynos PMU node is an interrupt, clock and PMU (Power Management Unit) controller, and these functionalities are supported by different drivers that matches the same compatible strings. Since commit 15cc2ed6dcf9 ("of/irq: Mark initialised interrupt controllers as populated") the OF core flags interrupt controllers registered with the IRQCHIP_DECLARE() macro as OF_POPULATED, so platform devices with the same compatible string as the interrupt controller will not be registered. This prevents the PMU platform device to be registered so the Exynos PMU driver is never probed. This breaks (among other things) Suspend-to-RAM. Fix this by clearing the OF_POPULATED flag in the PMU IRQ init callback, to allow the Exynos PMU platform driver to be probed. The patch is based on Philipp Zabel's "ARM: imx6: mark GPC node as not populated after irq init to probe pm domain driver".

2016-08-30xfs: track log done items directly in the deferred pending work itemDarrick J. Wong
Christoph reports slab corruption when a deferred refcount update aborts during _defer_finish(). The cause of this was broken log item state tracking in xfs_defer_pending -- upon an abort, _defer_trans_abort() will call abort_intent on all intent items, including the ones that have already had a done item attached. This is incorrect because each intent item has 2 refcount: the first is released when the intent item is committed to the log; and the second is released when the _done_ item is committed to the log, or by the intent creator if there is no done item. In other words, once we log the done item, responsibility for releasing the intent item's second refcount is transferred to the done item and /must not/ be performed by anything else. The dfp_committed flag should have been tracking whether or not we had a done item so that _defer_trans_abort could decide if it needs to abort the intent item, but due to a thinko this was not the case. Rip it out and track the done item directly so that we do the right thing w.r.t. intent item freeing. Signed-off-by: Darrick J.

2016-08-29drm: Remove drm_mode_object->atomic_countDaniel Vetter
It's only used in drm_mode_object_get_properties, and we can compute it there directly with a bit of code shuffling.

2016-08-29drm: Extract drm_mode_object.[hc]Daniel Vetter
Just for the struct drm_mode_object base class. The header file was already partially extracted to help untangle the include loops. v2: - Also move the generic get/set property ioctls. At first this seemed like a bad idea since it requires making drm_mode_crtc_set_obj_prop non-static. But eventually that will get split away too (like the connector version already is) for both crtc and planes. Hence I reconsidered. - drm_mode_object.[hc] instead of drm_modeset.[hc], which requires renaming the drm_modeset.h header I already started building up. This is more consistent (matches the name of the main structure), and I want to be able to use drm_modeset.[hc] for the basic modeset init/cleanup functionality like drm_mode_config_init.

2016-08-29drm/doc: Polish kerneldoc for encodersDaniel Vetter
- Move missing bits into struct drm_encoder docs. - Explain that encoders are 95% internal and only 5% uapi, and that in general the uapi part is broken. - Remove verbose comments for functions not exposed to drivers. v2: Review from Archit: - Appease checkpatch in the moved code. - Make it clearer that bridges are not exposed to userspace.

2016-08-29drm: Extract drm_encoder.[hc]Daniel Vetter
Same treatment as before. Only hiccup is drm_crtc_mask, which unfortunately can't be resolved until drm_crtc.h is less of a monster. Untangle the header loop with a forward declaration for that static inline.

2016-08-29fix:mailbox:bcm-pdc-mailbox:mark symbols static where possibleBaoyou Xie
We get 2 warnings when biuld kernel with W=1: drivers/mailbox/bcm-pdc-mailbox.c:472:6: warning: no previous prototype for 'pdc_setup_debugfs' [-Wmissing-prototypes] drivers/mailbox/bcm-pdc-mailbox.c:488:6: warning: no previous prototype for 'pdc_free_debugfs' [-Wmissing-prototypes] In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. so this patch marks these functions with 'static'.
