AlmaLinux 9.6 (kernels 5.14.0): Failed to locate the init task struct

Yoyo! I tested the current main branch, and unfortunately, the problem still occurs. My kernel version is 5.14.0-284.25.1.el9_2.x86_64 or 5.14.0-570.35.1.el9_6.x86_64. The same issue. Mem dump created with avml.

Any support will be very helpful. Thank you!

Start in src/operating_system/linux/operating_system.rs around lines 292 and 549, then read src/operating_system/linux/btf.rs around line 215. Reproduce the failure with an AlmaLinux 9.6 memory dump and trace BTF parsing and init_task resolution. Done means the reported kernels can create the operating system successfully with valid BTF symbols.
