[oi-dev] Panic on using fuse with todays "pkg update"

[Jean-Pierre André]

IMHO this is the culprit :

--- ../oi-include/sys/thread.h  2020-11-19 19:37:31.170054900 +0100
+++ thread.h.2  2022-09-12 10:48:43.877644300 +0200
@@ -158,7 +158,6 @@
         struct _kthread *t_intr; /* interrupted (pinned) thread */
         uint64_t        t_intr_start;   /* timestamp when time slice 
began */
         kt_did_t        t_did;  /* thread id for kernel debuggers */
-       caddr_t t_tnf_tpdp;     /* Trace facility data pointer */
         struct _kcpc_ctx *t_cpc_ctx;    /* performance counter context */
         struct _kcpc_set *t_cpc_set;    /* set this thread has bound */

Which changes the location of t_procp a few lines below in
struct _kthread

So have to recompile and set dependency for this to not occur again.
