CVE-2024-58089
In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix double accounting race when btrfs_run_delalloc_range() failed

[BUG]
When running btrfs with block size (4K) smaller than page size (64K,
aarch64), there is a very high chance to crash the kernel at
generic/750, with the following messages:
(before the call traces, there are 3 extra debug messages added)

[CAUSE]
The above warning is triggered immediately after the delalloc range
failure, this happens in the following sequence:

- Range [1568K, 1636K) is dirty

   1536K  1568K     1600K    1636K  1664K
   |      |/////////|////////|      |

  Where 1536K, 1600K and 1664K are page boundaries (64K page size)

- Enter extent_writepage() for page 1536K

- Enter run_delalloc_nocow() with locke
