>Description:
kdump(1) fails to recognize syssem, msgsys, shmsys, lfs, and nfs
system calls
>How-To-Repeat:
ktrace(1) a process that uses SYSV semaphores, SYSV messages,
SYSV shared memory, or lfs or nfs system calls, then use kdump(1)
to output the ktrace data file; kdump(1) will not output names
of semsys, msgsys, shmsys, nfssvc, getfh, or lfs_* sys calls.
>Fix:
Define NFS, SYSVSEM, SYSVMSG, SYSVSHM, and LFS before the line where
sys/kern/syscalls.c is included in kdump.c:
