They're fundamentally broken and should never ever be used.
* op==(weak, weak) is heterogeneous, but at the same time it's
unconstrained (!), may trigger UB (!) by doing a static_cast to a
type which isn't the actual type of the pointee, and may outright
crash (!) if the pointee has been deleted and there's virtual
inheritance.
* op==(weak, strong) compares the control blocks, i.e. does
"owner_equal" comparison, not pointer comparison. Now QSP doesn't
have support for aliasing, so the pointers stored by the smart
pointers themselves always point at the owner object.
Yet: given a QSharedPointer<T> that is the last owning pointer to T
and a QWeakPointer<T> that tracks it, if one resets the shared
pointer, then op==(wp, sp) will yield false (wp still points to the
control block, sp does not), but op==(wp.lock(), sp) will yield
true (both shared pointers are null). That doesn't make any sense.
I'm leaving op==(wp, std::nullptr_t) in as a shorthand to check if the
weak pointer is expired, but might deprecate that as well in a future
commit.
[ChangeLog][QtCore][QWeakPointer] The (in)equality operators of
QWeakPointer have been deprecated. Always upgrade a QWeakPointer to a

Instead of the previous realpath() comparison resulting from the symlink
processing. parseMountInfo() was extracting the device number from
/proc, so this information was already readily available.
We must take care of anonymous block devices (major == 0). Certain
filesystems, such as btrfs, always use them, so we must still stat() the
device path to get the real block device.
This implementation assumes that udev only creates entries in the
/dev/disks/by-label directory that are symlinks to real devices, but
that must already be the case because they are in /dev in the first
place. An alternative implementation would be to compare the inode and
host device (st_dev) of the entry, if different /dev entries could have
different labels. I don't think that's possible. But multiple /dev
entries for the same device is definitely possible.

Linux allows admins to mount new filesystems over non-empty paths
(though I managed to do so on FreeBSD and macOS too), so we must find
the most recent mount that applies to this path instead of the longest
matching mountpoint. We do that by scanning the /proc/self/mountinfo
list backwards and thus any matching isParentOf() must be the correct
one.
# mkdir -p /tmp/foo/bar
# mount -t tmpfs tmpfs /tmp/foo/bar
# mount -t tmpfs -o size=1M tmpfs /tmp/foo

But we must guard against an earlier mount still being (somehow)
accessible. We've seen this in the CI, where /run is earlier than / but
still somehow accessible -- I guess this is one or a pair of mount
--move.
An additional benefit is that don't even attempt to compare to the
virtual filesystems mounted by the system early after boot, if what
we're looking for isn't the root.

When a child window is made visible without its parent having been

But if a child window is explicitly created, we create the parent
first. And creating the parent will in turn apply visibility to
all children that had their visibility deferred. Which includes
creating the child.
This results in child -> parent -> child creation recursion,
which means that when we return from creating the parent window
we already have a platform window for our child, and should

When running on operating systems that don't offer modern APIs, we need
to round up to ensure we don't under-sleep and wake up before the timers
actually expire. In most cases, this is not a big deal because we'd go
right back to sleep and then wake up again.
The problem is that this new sleep would be for a duration of 0
milliseconds, so we'd end up busy-waiting until the timers do expire.
It's for less than 1 ms, but it's still power-consuming.
It's also perceptible when someone uses processEvents(), because we
could end up saying we didn't process anything, despite waiting for more
events. Since that violates the guiding rule for processEvents() (don't
ever use it), I don't consider this a big deal.
