It turns out that preserving framebuffers after the rmfb call breaks vmwgfx userspace. This was originally introduced because it was thought nobody relied on the behavior, but unfortunately it seems there are exceptions. drm_framebuffer_remove may fail with -EINTR now, so a straight revert is impossible. There is no way to remove the framebuffer from the lists and active planes without introducing a race because of the different locking requirements. Instead call drm_framebuffer_remove from a workqueue, which is unaffected by signals. Changes since v1: - Add comment. Changes since v2: - Add fastpath for refcount = 1. (danvet) Changes since v3: - Rebased. - Restore lastclose framebuffer removal too. Cc: stable@vger.kernel.org #v4.4+ Fixes: 13803132 ("drm/core: Preserve the framebuffer after removing it.")

Don't just free the connector when we get the destroy callback. Drop a reference to it, and set it's mst_port to NULL so no more mst work is done on it. v2: core mst accepts NULLs fine. Cleanup EDID code properly. v3: drop the extra reference we were taking. Reviewed-by:

Take a reference when setting a crtc on a connecter, also take one when duplicating if a crtc is set, and drop one on destroy if a crtc is set. v2: take Daniel Stone's advice and simplify the ref/unref dances, also take care of NULL as connector to state reset. v3: remove need for connector NULL check.

Ofc I promise just a few leftovers for drm-misc and somehow it's the biggest pull. But really mostly trivial stuff: - MAINTAINERS updates from Emil - rename async to nonblock in atomic_commit to avoid the confusion between nonblocking ioctl and async flip (= not vblank synced), from Maarten. Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation.

Finally all the core gem and a lot of drivers are entirely free of dev->struct_mutex depencies, and we can start to have an entirely lockless unref path. To make sure that no one who touches the core code accidentally breaks existing drivers which still require dev->struct_mutex I've made the might_lock check unconditional. While at it de-inline the ref/unref functions, they've become a bit too big. v2: Make it not leak like a sieve. v3: Review from Lucas: - drop != NULL in pointer checks. - fixup copypasted kerneldoc to actually match the functions. v4: Add __drm_gem_object_unreference as a fastpath helper for drivers who abolished dev->struct_mutex, requested by Chris. v5: Fix silly mistake in drm_gem_object_unreference_unlocked caught by intel-gfx CI - I checked for gem_free_object instead of gem_free_object_unlocked ...
