c4a2f8db8d Increased default minfree to 8%. 1995-03-10 22:18:16 +00:00
dg
251a107ca6 The threshold for switching from time-space and space-time is too small
when minfree is 5%...so make it stay at space in this case.

b017660c3e Patch to fix quota panic from Mike Karels:
allow Q_SYNC regardless of "target" uid, we allow it with -1;
fix bug that caused all ops to refer to user quotas, not group.

2c992ab302 Add a dummy ___bb_init_func for BB profiling of the kernel.
To use this: recompile src/gnu/usr.bin/cc, compile your kernel.  The
files you want to profile should be compiled with '-a -g'.  "strip -x"
the kernel and run.  You don't need to profile all files in the kernel.
My next commit is the program to extract the data from the running kernel.

73699a95c4 Clean up and improve the namecache.

namecache doesn't get trashed.  It used to be that it wasn't a problem, but
the only vnodes getting released these days are directories and things which
gets forced out of the VM/cache.  The latter is not numerous enough to keep
the pool of vnodes needed for the namecache sufficiently big.

2. Purge invalid entries in the namecache as soon as we notice them.  This
avoids a stale entry pushing out a valid entry on the LRU list.

3. Speed up the lookup in the namecache by avoid a special case branch.

4. Make the cache purge routines do the thing they're supposed to, and in
a decently efficient manner.

5. Make the size of the namecache follow the number of vnodes, so that we
can always point to all the vnodes we have in core.

6. Readability has gone way up.

7. Added a "options NCH_STATISTICS" feature that will gather more
detailed statistics on the performance of the namecache.

22174e3f91 Set VAGE flag when pager is destroyed. This usually happens when an
object has fallen off the end of the cached list - this is likely the
last reference to the vnode and it should be reused before non file

Fix it so that calls to extend_get won't dereference 0 when "swap
on sd.." calls sdsize() on systems with no SCSI devices.

This probably really fixes Poul's "boot with no SCSI" problem.
