https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264094 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markj@FreeBSD.org --- Comment #19 from Mark Johnston <markj@FreeBSD.org> --- (In reply to Jessica Clarke from comment #10) Can you see offhand why the symbol (vnet_entry_htcp_adaptive_backoff) is preemptible in the first place? For arm64 KLDs, VNET_DEFINE_STATIC is hack= ed up to omit the static qualifier. But the linker changes the binding of the symbol: cc_htcp.o: 73: 0000000000000000 4 OBJECT GLOBAL DEFAULT 5 vnet_entry_htcp_adaptive_backoff cc_htcp.ko: 35: 0000000000021520 4 OBJECT LOCAL DEFAULT 11 vnet_entry_htcp_adaptive_backoff and local symbols have hidden visibility by default. I'm not sure offhand = why it's changed. I guess -Bsymbolic would have that effect, but we don't spec= ify it. --=20 You are receiving this mail because: You are on the CC list for the bug.=
