commit 5de0434bc064606d6b7467ec3e5ad22963a18c04 upstream.
When the send protocol versioning was added in 5.16 e77fbf990316 ("btrfs: send: prepare for v2 protocol"), the 32/64bit compat code was not updated (added by 2351f431f727 ("btrfs: fix send ioctl on 32bit with 64bit kernel")), missing the version struct member. The compat code is probably rarely used, nobody reported any bugs.
