BZZZT!! Try again.
peter@overcee[12:35pm]~/releng_4/sys/conf-110> ls param.c
ls: param.c: No such file or directory
param.c was moved to kern/subr_param.c and is fully dynamic, and already
has these changes.
TUNABLE_INT_DECL() should be TUNABLE_INT() and is using the old syntax.
If you're going to submit stuff, please at least do us the courtesy to make
sure it is relative to recent source trees. This change was made quite some
time ago on both -current and RELENG_4.
FYI: kern/subr_param.c:
...
int maxprocperuid; /* max # of procs per user */
int maxfiles; /* sys. wide open files limit */
int maxfilesperproc; /* per-proc open files limit */
int ncallout; /* maximum # of timer events */
...
/* The following can be overridden after boot via sysctl */
maxproc = NPROC;
TUNABLE_INT_FETCH("kern.maxproc", &maxproc);
maxfiles = MAXFILES;
TUNABLE_INT_FETCH("kern.maxfiles", &maxfiles);
maxprocperuid = maxproc - 1;
maxfilesperproc = maxfiles;
...
