Control: found -1 2.13.9-1
Hi,
the bullseye kernel at some point seems to have enabled
-Werror=implicit-function-declaration, causing the module to now fail to
build:

This also affects the version in bookworm. On distupgrades from bullseye
to bookworm, kernels and headers from both releases are installed and
therefore lttng-modules-dkms/bookworm needs to be able to build a module
for the bullseye kernel.
(lttng-modules-dkms/bookworm builds fine for 6.1.0-31-amd64, the
bookworm kernel)
Linux commit 460b4f812a9d473d4b39d87d37844f9fc30a9eb3 from v5.11-rc1 has
been backported as c4716bb296504cbc64aeefb370df44e821214c44 to
v5.10.220
A possible fix for bookworm could be in include/wrapper/fdtable.h to
replace
#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,11,0))
with
#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,10,220))
