Merge with Lite2 + local changes
1998-03-01 02:20:01 +00:00
ed1d38cfe3
Add "storage" arguments (all NULL) to pool_create() and pool_prime().
1998-02-19 23:56:37 +00:00
1e3e1bfe09
Include the NFS option header.
1998-02-19 00:55:04 +00:00
443a2a02f4
"pool" routines moved to kern/subr_pool.c
1997-12-15 11:18:41 +00:00
5d1352c448
Guard against synchronous I/O completetion per swap-device.
1997-12-02 13:47:37 +00:00
1736bb9de8
Make the code a bit more readable.
1997-12-01 17:10:48 +00:00
d4a6f93147
Make sure the damned buffer heads are initialized...
1997-12-01 16:33:15 +00:00
46f604677d
Avoid several race conditions, especially when a transaction ends in error.
...
Guard sw_reg_start() against synchronous completions of the device
strategy routines, avoiding possibly boundless recursion.
1997-11-29 00:35:43 +00:00
97d2a58201
Fix slight argument bogosity with getgroups(), setgroups(), select(),
...
and swapctl(). For the former three, they use an 'int' in their user-land
prototype which was a 'u_int' in the kernel, which screwed up automatic
generation/checking of lint syscall stubs. For the latter, the user-land
prototype uses a "const char *", but the syscall just used "char *".
From Chris Demetriou <cgd@pa.dec.com>.

A `simplelock' suffices for most swap device list traversals, as noted
...
by Chuck Cranor.
Use an exclusive (long-term) lock before applying changes to the swap
lists. This lock is also used by the stats system call because of possible
blocking in copyout().
1997-10-17 19:06:05 +00:00
dfbda96da0
Use `long' to cast a pointer to an integer and back.
1997-10-14 08:50:18 +00:00
e95c79e586
Keep a private pool of auxiliary resources (vndxfer & vndbuf structures)
...
used to setup I/O to regular files.
Implemented in a somewhat generic way, for what it's worth.
1997-10-13 19:15:19 +00:00
55c881fbd2
when creating the per-device extent, use from 0 to nblks, and then
...
extent_alloc_region() any skipped space. this is (basically) what
the previous swap code did (with rmaps rather than extents).
1997-10-10 13:16:24 +00:00
74f573d85d
remove advertising clause from all my licenses.
1997-10-10 05:39:47 +00:00
3bd11220b6
Don't print a message if the user attempts SWAP_OFF. Return an error
...
instead.
1997-06-17 03:37:07 +00:00
c61704d37c
Remove the code that sets dumpdev, for two reasons:
...
- It was incorrect. A dev_t should _never_ be compared against
NULL, as 0 is a valid value (major 0, minor 0).
- The operator mave have _intentionally_ set dumpdev to "none"
(i.e. NODEV), and setting it the first time a VBLK swap device
is added would break the semantics.
setroot() deals with all dump device selection. Dumps and swap are now
in no way related.
1997-06-16 20:21:55 +00:00
c78d0720ff
- set dumpdev if not already set
...
- don't use nocoalease (from thorpej).
- fix priority list management (from pk).
- update comment for swapoff.
- free swap device extent name safely (from thorpej).

As long as we actually use `swapdev_vp', initialize it.
1997-06-13 15:37:17 +00:00

bring mrg-vm-swap2 onto mainilne.
1997-06-12 14:51:20 +00:00

Change to not require including <sys/dmap.h>
1997-04-17 00:12:50 +00:00
b7a5b84750
Treat the nswdev == 0 case like the nswap == 0 case; don't panic, just
...
report no swap space. Suggested by Leo Weppleman <leo@netbsd.org>.
1997-01-22 07:28:21 +00:00
9ab047883b
Fix unused variable -Wxxx failure when MINIROOTSIZE defined.

Make system calls conform to a standard prototype and bring those
...
prototypes into scope.
1995-09-19 21:57:36 +00:00

Preserve miniroot when (swdevt[i].sw_vp == rootvp)
1995-09-18 21:21:00 +00:00
4ec7eec85b
don't forget the 'dev' argument to physio(). pointed out by der Mouse
...
and others.
1995-07-19 13:04:02 +00:00
7263209ce6
Make each disk and tape driver define its own read and write functions.
...
Deprecate rawread() and rawwrite() completely. Remove d_strategy from cdevsw to
force the abstraction barrier.
1995-07-04 07:15:28 +00:00
4b5b562e89

1994-05-23 03:11:20 +00:00
95fcf16b66
add sequential swap device support, supplied by hibler many moons ago.
...
(Note that it needs config support, too, which isn't there yet, but
might be soon...) Also, general cleanup. use NODEV to terminate swdevt,
so that sparc port (and future) is happy.
1994-04-25 23:53:51 +00:00
3dda0064a5
Convert mount, vnode, and buf structs to use <sys/queue.h>. Also,
...
some knf and structure frobbing to do along with it.
