pager(). Almost completely rewrote vm_mmap(); when John gets done with
the bottom half, it will be a complete rewrite. Deprecated most use of
vm_object_setpager(). Removed side effect of setting object persist
in vm_object_enter and moved this into the pager(s). A few other
cosmetic changes.
returned to user mode without enabling ASTs. The problem fixed itself
at the next syscall or non-FPU trap, if any. It hung the system for
a test process that masked SIGFPE's and divided by zero. The faulting
division was returned to endlessly and this gave plently of opportunities
for the swi_ast_phantom case to be reached; after it was reached the
system hung because the ASTs for preemption and SIGINT handling were
disabled.
via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)
Now it is at least possible to prohibit one user opening maxfiles

In diffutils 2.6 and 2.7, diff3 -A complains about identical overlapping
changes. They're different from the ancestor but not from each other...
Why bother? The patch below fixes this nonsense and preserves [B]ackwards
compatiblity with the -B flag (also --show-bogus-conflicts).
Party on...

Since functions will come and go from libcompat as they are deprecated
it makes no sense to build a shared library out of it as it will change.
Based on freedback from Terry and Jonas on the mailing lists.
Slight change to reverse collapsing so that vm_object_deallocate doesn't
have to be called recursively.
Removed half of a previous fix - the renamed page during a collapse doesn't
need to be marked dirty because the pager backing store pointers are copied
- thus preserving the page's data. This assumes that pages without backing
store are always dirty (except perhaps for when they are first zeroed, but
this doesn't matter).
Switch order of two lines of code so that the correct pager is removed
from the hash list. The previous code bogusly passed a NULL pointer to
vm_object_remove(). The call to vm_object_remove() should be unnecessary
if named anonymous objects were being dealt with correctly. They are
currently marked as OBJ_INTERNAL, which really screws up things (such as
this).
requires complications to adjust the offsets to relative when a block
containing the label is read and back to absolute when such a block is
written. The adjustment is not made on the whole disk slice.
Don't allow setting the offset of partition C to nonzero in in-core labels.
This will cause some (nonstandard) disktab entries to fail. They will
need to be changed to have relative offsets (and no partitions outside
of the slice).
Don't write protect the (nonexistent) label on the whole disk slice.
Writing labels and bootstraps should work right now (except if there is
no DOSpartition table).
just thinking about it.
Two changes need to be made to allow 'config kernel swap generic' to
work properly without requiring any compile-time flags:
/usr/src/usr.sbin/config/mkswapconf.c: we need to define a dummy stub
for the setconf() function to replace the one in swapgeneric.c that
isn't available in non-generic configurations.
/usr/src/sys/i386/i386/autoconf.c: the -a boot flag causes setroot()
to be skipped and lets setconf() prompt the user for a root device.
If you skip setroot() in a non-generic kernel, you could get severely
hosed. To avoid this, we silently ignore the -a flag if rootdev != NODEV.
(rootdev is always initialized to NODEV in swapgeneric.c, so if
we find that rootdev is something other than NODEV, we know we're
not using a generic configuration.)
