Description

According to changelogs, SEND_SIG_FORCED should be removed from 2.11.0.
It still exists in the code.
This causes build errors while compiling against 4.18 on centos 8.1.

I double-checked, and vanilla v4.18 and v4.18.20 kernels implement SEND_SIG_FORCED, as expected by LTTng-modules. It is removed from vanilla kernels starting from v4.20.

Note that RHEL and CentOS kernels integrate significant modifications from mainline kernels, and we need to track those distribution-specific changes very closely.

We need to identify the exact range of versions which include this change in the RHEL kernels so we can use the LTTNG_RHEL_KERNEL_RANGE() macro accordingly.
