https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291273 Rupesh Pilania <rupeshpilania@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rupeshpilania@gmail.com --- Comment #2 from Rupesh Pilania <rupeshpilania@gmail.com> --- I’ve tested the fixes by disabling symbol-leak suppression (debug.link_elf_leak_locals=0 and debug.link_elf_obj_leak_locals=0) to ensure unresolved symbols become visible. With the updated EXPORT_SYMS entries added to sys/modules/p9fs/Makefile, both modules now load successfully without any undefined symbol errors.
