4fa05a67b5 dma-buf: revert "return only unsignaled fences in dma_fence_unwrap_for_each v3"
This reverts commit 8f61973718.

It turned out that this is not correct. Especially the sync_file info
IOCTL needs to see even signaled fences to correctly report back their
status to userspace.

Instead add the filter in the merge function again where it makes sense.

Fixes resume from hibernate failing on (at least) TU102, where cursor
channel init failed due to being performed before the core channel.

Not solid idea why suspend-to-ram worked, but, presumably HW being in

24f4b40ec2 Merge branch 'hot-fixes' (fixes for rc6)
This is a collection of three fixes for small annoyances.

Two of these are already pending in other trees, but I really don't want
to release another -rc with these issues pending, so I picked up the
patches for these things directly.  We'll end up with duplicate commits
eventually, I prefer that over having these issues pending.

The third one is just me getting rid of another BUG_ON() just because it
was reported and I dislike those things so much.

* merge 'hot-fixes' branch:
  ida: don't use BUG_ON() for debugging
  drm/aperture: Run fbdev removal before internal helpers
  ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()

fc82bbf4de ida: don't use BUG_ON() for debugging
This is another old BUG_ON() that just shouldn't exist (see also commit
a382f8fee4: "signal handling: don't use BUG_ON() for debugging").

In fact, as Matthew Wilcox points out, this condition shouldn't really
even result in a warning, since a negative id allocation result is just
a normal allocation failure:

  "I wonder if we should even warn here -- sure, the caller is trying to
   free something that wasn't allocated, but we don't warn for
   kfree(NULL)"

and goes on to point out how that current error check is only causing
people to unnecessarily do their own index range checking before freeing
it.

This was noted by Itay Iellin, because the bluetooth HCI socket cookie
code does *not* do that range checking, and ends up just freeing the
error case too, triggering the BUG_ON().

The HCI code requires CAP_NET_RAW, and seems to just result in an ugly
splat, but there really is no reason to BUG_ON() here, and we have
generally striven for allocation models where it's always ok to just do

    free(alloc());

even if the allocation were to fail for some random reason (usually
obviously that "random" reason being some resource limit).

Fixes: 88eca0207c ("ida: simplified functions for id allocation")

f5a4618587 kbuild: remove unused cmd_none in scripts/Makefile.modinst
Commit 65ce9c3832 ("kbuild: move module strip/compression code into
scripts/Makefile.modinst") added this unused code.

Perhaps, I thought cmd_none was useful for CONFIG_MODULE_COMPRESS_NONE,
but I did not use it after all.

84499c5d22 drm/aperture: Run fbdev removal before internal helpers
Always run fbdev removal first to remove simpledrm via sysfb_disable().
This clears the internal state.

The later call to drm_aperture_detach_drivers() then does nothing.
Otherwise, with drm_aperture_detach_drivers() running first, the call to
sysfb_disable() uses inconsistent state.

Example backtrace show below:

d785a773be io_uring: check that we have a file table when allocating update slots
If IORING_FILE_INDEX_ALLOC is set asking for an allocated slot, the
helper doesn't check if we actually have a file table or not. The non
alloc path does do that correctly, and returns -ENXIO if we haven't set
one up.

Do the same for the allocated path, avoiding a NULL pointer dereference
when trying to find a free bit.

Pull fscache fixes from David Howells:

 - Fix a check in fscache_wait_on_volume_collision() in which the
   polarity is reversed. It should complain if a volume is still marked
   acquisition-pending after 20s, but instead complains if the mark has
   been cleared (ie. the condition has cleared).

   Also switch an open-coded test of the ACQUIRE_PENDING volume flag to
   use the helper function for consistency.

 - Not a fix per se, but neaten the code by using a helper to check for
   the DROPPED state.

 - Fix cachefiles's support for erofs to only flush requests associated
   with a released control file, not all requests.

 - Fix a race between one process invalidating an object in the cache
   and another process trying to look it up.
