The default case will have the .c wrappers still. If you define WITHOUT_SYSCALL_COMPAT, the .c wrappers will go away and libc will make direct syscalls. After 7-stable starts, the direct syscall method will be default. Approved by: re (kensmith)

After 7-stable starts, the direct syscall method will be default.

Add the mlockall() and munlockall() system calls. 2003-08-11T07:14:08+00:00 Bruce M Simpson bms@FreeBSD.org 2003-08-11T07:14:08+00:00 abd498aa7127b03d6c0593cdb8f8308dd65758c6 - All those diffs to syscalls.master for each architecture *are* necessary. This needed clarification; the stub code generation for mlockall() was disabled, which would prevent applications from linking to this API (suggested by mux) - Giant has been quoshed. It is no longer held by the code, as the required locking has been pushed down within vm_map.c. - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES to express their intention explicitly. - Inspected at the vmstat, top and vm pager sysctl stats level. Paging-in activity is occurring correctly, using a test harness. - The RES size for a process may appear to be greater than its SIZE. This is believed to be due to mappings of the same shared library page being wired twice. Further exploration is needed. - Believed to back out of allocations and locks correctly (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).
