It is another reason for NO_SPACE case.
When we found enough free space in loop and saved them to
max_hole_start/size before, and tail space contains pending extent,
origional innocent max_hole_start/size are reset in retry.
As a result, find_free_dev_extent() returns less space than it can,
and cause NO_SPACE in user program.

So just bail out of the clone ioctl if the length of the region to clone
is zero, without locking any extent range, in order to prevent this issue
(same behaviour as a pwrite with a 0 length for example).
This is trivial to reproduce. For example, the steps for the test I just
made for fstests:
mkfs.btrfs -f SCRATCH_DEV
mount SCRATCH_DEV $SCRATCH_MNT
touch $SCRATCH_MNT/foo
touch $SCRATCH_MNT/bar
$CLONER_PROG -s 0 -d 4096 -l 0 $SCRATCH_MNT/foo $SCRATCH_MNT/bar
umount $SCRATCH_MNT

If we pass a length of 0 to the extent_same ioctl, we end up locking an
extent range with a start offset greater then its end offset (if the
destination file's offset is greater than zero). This results in a warning
from extent_io.c:insert_state through the following call chain:
btrfs_extent_same()
btrfs_double_lock()
lock_extent_range()
lock_extent(inode->io_tree, offset, offset + len - 1)
lock_extent_bits()
__set_extent_bit()
insert_state()
--> WARN_ON(end < start)
This leads to an infinite loop when evicting the inode. This is the same
problem that my previous patch titled

but for the extent_same ioctl instead of the clone ioctl.

While searching for extents to clone we might find one where we only use
a part of it coming from its tail. If our destination inode is the same
the source inode, we end up removing the tail part of the extent item and
insert after a new one that point to the same extent with an adjusted
key file offset and data offset. After this we search for the next extent
item in the fs/subvol tree with a key that has an offset incremented by
one. But this second search leaves us at the new extent item we inserted
previously, and since that extent item has a non-zero data offset, it
it can make us call btrfs_drop_extents with an empty range (start == end)

This is wrong because we should not process the extent item that we just
inserted previously, and instead process the extent item that follows it
in the tree
For example for the test case I wrote for fstests:
bs=$((64 * 1024))
mkfs.btrfs -f -l $bs -O ^no-holes /dev/sdc
mount /dev/sdc /mnt
xfs_io -f -c "pwrite -S 0xaa $(($bs * 2)) $(($bs * 2))" /mnt/foo
$CLONER_PROG -s $((3 * $bs)) -d $((267 * $bs)) -l 0 /mnt/foo /mnt/foo
$CLONER_PROG -s $((217 * $bs)) -d $((95 * $bs)) -l 0 /mnt/foo /mnt/foo
The second clone call fails with -EEXIST, because when we process the
first extent item (offset 262144), we drop part of it (counting from the
end) and then insert a new extent item with a key greater then the key we
found. The next time we search the tree we search for a key with offset
262144 + 1, which leaves us at the new extent item we have just inserted
but we think it refers to an extent that we need to clone.
Fix this by ensuring the next search key uses an offset corresponding to
the offset of the key we found previously plus the data length of the
corresponding extent item. This ensures we skip new extent items that we
inserted and works for the case of implicit holes too (NO_HOLES feature).
A test case for fstests follows soon.

This provides a nice boost to mesa in swap bound scenarios (as mesa
throttles itself to the previous frame and given the scenario that will
complete shortly). It will also provide a good boost to systems running
with semaphores disabled and so frequently waiting on the GPU as it
switches rings. In the most favourable of microbenchmarks, this can
increase performance by around 15% - though in practice improvements
will be marginal and rarely noticeable.
v2: Account for user timeouts
v3: Limit the spinning to a single jiffie (~1us) at most. On an
otherwise idle system, there is no scheduler contention and so without a
limit we would spin until the GPU is ready.

This change makes it so that instead of using smp_wmb/rmb which varies
depending on the kernel configuration we can can use dma_wmb/rmb which for
most architectures should be equal to or slightly more strict than
smp_wmb/rmb.
The advantage to this is that these barriers are available to uniprocessor
builds as well so the performance should improve under such a
configuration.

__ex_table is a simple table section where each entry is a pair of
addresses - the first address is an address which can fault in kernel
space, and the second address points to where the kernel should jump to
when handling that fault. This is how copy_from_user() does not crash the
kernel if userspace gives a borked pointer for example.
If one of these addresses point to a non-executable section, something is
seriously wrong since it either means the kernel will never fault from
there or it will not be able to jump to there. As both cases are serious
enough, we simply error out in these cases so the build fails and the
developper has to fix the issue.
In case the section is executable, but it isn't referenced in our list of
authorized sections to point to from __ex_table, we just dump a warning
giving more information about it. We do this in case the new section is
executable but isn't supposed to be executed by the kernel. This happened
with .altinstr_replacement, which is executable but is only used to copy
instructions from - we should never have our instruction pointer pointing
in .altinstr_replacement. Admitedly, a proper fix in that case would be to
just set .altinstr_replacement NX, but we need to warn about future cases

From intel_atomic_check, call intel_atomic_setup_scalers() to
assign scalers based on staged scaling requests. Fail the
transaction if setup returns error.
Setting up of scalers should be moved to atomic crtc check once
atomic crtc is ready.

Added intel_atomic_setup_scalers to setup scalers based on
staged scaling requests from a crtc and its planes. If staged
requests are supportable, this function assigns scalers to
requested planes and crtc. Note that the scaler assignement
itself is staged into crtc_state and respective plane_states
for later commit after all checks have been done.
overall high level flow:
- scaler requests are staged into crtc_state by planes/crtc
- check whether staged scaling requests can be supported
- add planes using scalers that aren't in current transaction
- assign scalers to requested users
- as part of plane commit, scalers will be committed
(i.e., either attached or detached) to respective planes in hw
- as part of crtc_commit, scaler will be either attached or detached
to crtc in hw
crtc_compute_config calls intel_atomic_setup_scalers() to start
scaler assignments as per scaler state in crtc config. This call
should be moved to atomic crtc once it is available.
v2:
-removed a log message (me)
-changed input parameter to crtc_state (me)
v3:
-remove assigning plane_state returned by drm_atomic_get_plane_state (Matt)
-fail if there is an error from drm_atomic_get_plane_state (Matt)

-changes to align with updated scaler structure (Matt, me)
v5:
-added addtional checks before enabling HQ mode (me)
-added comments to enable HQ mode (Matt)

crtc_state is cleared during mode set which wipes out complete
scaler state too. This is causing issues. To fix, ensure scaler
state is preserved because it contains not only crtc
scaler usage, but also planes using scalers on this crtc.
