Bug#1090957: nvidia-fs-dkms: Module fails to build with kernel 6.12.5

[Marc Glisse]

Package: nvidia-fs-dkms
Version: 2.16.1~12.2.0-3
Severity: important

Dear Maintainer,

during the usual `apt upgrade` today, I got an error

Building module(s)........(bad exit status: 2)
Failed command:
'make' -j16 KVER=6.12.5-amd64 IGNORE_CC_MISMATCH='1'
Error! Bad return status for module build on kernel: 6.12.5-amd64 (x86_64)
Consult /var/lib/dkms/nvidia-fs/2.16/build/make.log for more information.
dkms autoinstall on 6.12.5-amd64/x86_64 succeeded for nvidia-current
dkms autoinstall on 6.12.5-amd64/x86_64 failed for nvidia-fs(10)
Error! One or more modules failed to install during autoinstall.
Refer to previous errors for more information.
dkms: autoinstall for kernel: 6.12.5-amd64 failed!

dpkg: error processing package linux-image-6.12.5-amd64 (--configure):

make.log has error messages like

/var/lib/dkms/nvidia-fs/2.16/build/nvfs-core.c:915:31: error: ‘FMODE_UNSIGNED_OFFSET’ undeclared (first use in this function); did you mean ‘FOP_UNSIGNED_OFFSET’?
/var/lib/dkms/nvidia-fs/2.16/build/nvfs-core.c:1566:16: error: ‘struct fd’ has no member named ‘file’
/var/lib/dkms/nvidia-fs/2.16/build/nvfs-core.c:916:1: error: control reaches end of non-void function [-Werror=return-type]

I expect this may already be fixed in newer versions of the upstream
package?
