Machine independent part of fix for PR 6152 (gdb doesn't work on machines

the syncing operation for "curproc", too; this way more code can be shared.

Workaropund fix for PR #5239 from <minoura@kw.netlaputa.ne.jp>:
...
stop null_node_create() from locking the nullfs mountpoint multiple

during mount of a nullfs filesystem. nullfs filesystems are still as
buggy as ever (e.g., see PR# 4907) but this you at least mount them.

Rework the way kernel include files are installed. In the new method,
...
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
...
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
cleanup.
* Require the file system to decide whether or not linking and unlinking of
directories is allowed, and disable it for all current file systems.

splnet --> splsoftnet
1995-08-12 23:59:09 +00:00
e9d17d38b5
avoid unnecessary aging of buffers. This used to make sense, when buffer
...
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow. Suggested by Bob Baron.
1995-07-24 21:19:27 +00:00
3a99ca568b
this README has been unnecessary for a while.

1995-06-18 14:45:14 +00:00
e729deedb2
Fix a condition where union_updatevp() would reinsert the node onto the
...
wrong hash chain, by not swapping the hash values. Noted by John Kohl, but
fixed differently.
1995-06-02 02:39:20 +00:00
95ded74f58
Moved egid credential from cr_groups[0] to new field cr_gid. POSIX.1
...
requires that sgid executables and the setuid() syscall *not* change
the supplemental group list.
1995-06-01 22:43:30 +00:00
e9f4bff2cc

1995-05-30 10:28:15 +00:00
7c7b203953
Make sure un_dircache is set after union_dircache(), to avoid stranding
...
references and the dircache buffer.
1995-05-30 09:37:02 +00:00
6760c93567
When a file is removed from the upper layer, make sure to release the
...
reference to it. From John Kohl.
1995-05-30 09:07:10 +00:00
eb310b67a7
