Or improve its portability (does it really need to look inside proc_t?)
This is only needed to get the pid of the current process, through
"curproc->p_pidp->pid_id", with curproc defined as threadp()->t_procp
The pid is passed to user level so that it can determine the credentials
of the caller (e.g. the list of groups to which it belongs).
A reasonable way is to define a curpid() system function (not a macro
nor an inliner), similar to vn_is_opened() or vn_has_other_opens()
which are used to hide the locations of v_rdcnt and v_wrcnt located
in struct vnode beyond the immutable locations.
There would also be other fields to consider, in particular p_rctls
from struct proc.

We could integrate fuse into illumos to avoid that kind of thing.

Which changes the location of t_procp a few lines below in

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

This is accessing t_procp->p_pidp, so it looks very much like the
kernel has been recompiled after <sys/thread.h> or <sys/proc.h>
have been changed, without the fuse kernel module being recompiled
(or at least being downloaded).
You probably only need to recompile with current headers and download.
This has already occurred before. Where is the dependency preventing
this from occurring missing ?

Hello!
I made a pkg update today, and was surprised to get a panic on using
my fuse file system "exfat" on USB3, which i use for 1-2 years now.
Maybe some illumos patch is causing this (?)
I have build the exfat bits on the new BE, to no success..
