For lttng-modules-2.13.18

I have this error with kernel version 5.14.0-582.el9.x86_64:

lttng-modules-2.13.18/src/lttng-statedump-impl.c:415:20: error: 'dev_base_lock' undeclared (first use in this function); did you mean 'device_lock'?

I got it to create modules by changing the condition on line 396

Original:
#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(6,9,0))

Modification:
#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(6,9,0)) || (LTTNG_LINUX_VERSION_CODE == LTTNG_KERNEL_VERSION(5,14,0))

I don't know how you distinguish the version after the dash character for RHEL kernels.
