yamt 09ff411cf6 - g/c stale function prototypes. 
- rename UVM_PAGE_HASH_PENALTY to UVM_PAGE_TREE_PENALTY.
 2009-01-16 02:33:14 +00:00
rmind b5eb577d50 - Initialize pool subsystem and kmem(9) earlier, when UVM is up enough. 
- Remove uao_hashinit() workaround used for anon-objects.
- Replace malloc with kmem.

OK by <yamt>.

ad 1c7f0a02df Use pool_cache. 2008-06-25 13:21:04 +00:00
ad 06c343ac94 vm_page: put TAILQ_ENTRY into a union with LIST_ENTRY, so we can use both. 2008-06-04 12:41:40 +00:00
ad e1be8408a0 uao_reference, uao_detach: we don't do reference counting on kernel objects, 
so don't lock them needlessly.

ad e071d39c84 - Convert hashinit() to use kmem_alloc(). The hash tables can be large 
and it's better to not have them in kmem_map.
- Convert a couple of minor items along the way to kmem_alloc().
- Fix some memory leaks.

hubertf 142c2a33ba Remove duplicate #includes, patch contributed in private mail 
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.

there seems to be far more people who don't want to edit
their kernel config files than i thought.

simonb b5d0e6bf06 Initialise (most) pools from a link set instead of explicit calls 
to pool_init.  Untouched pools are ones that either in arch-specific
code, or aren't initialiased during initial system startup.

drochner da03a1c8cf Fix a reversed logic in swap deallocation which could lead to 
uvm_swap_free() being called with a zero slot; this might have been
the reason for crashes with sysvshm and heavy swapping.
(PR kern/22752 by Tom Spindler)
Confirmed by Chuck Silvers.

pk 9a4aea0127 When retiring a swap device with marked bad blocks on it we should update 
the `# swap page in use' and `# swap page only' counters.  However, at the
time of swap device removal we can no longer figure out how many of the
bad swap pages are actually also `swap only' pages.

So, on swap I/O errors arrange things to not include the bad swap pages in
the `swpgonly' counter as follows: uvm_swap_markbad() decrements `swpgonly'
by the number of bad pages, and the various VM object deallocation routines
do not decrement `swpgonly' for swap slots marked as SWSLOT_BAD.
