src/sys/dev/pst/pst-raid.c, branch releng/8.0

Flush the queue of minor fixes to pst.

2004-09-15T15:39:28+00:00

Change the disk(9) API in order to make device removal more robust.

2004-02-18T21:36:53+00:00

Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

Dont re-arm the timeout twice on a timeout error.

The problem with the first timeout still exsists though, but not
it doesn't enter a groundbound spin loop :)

Use __FBSDID().

Also some minor style cleanups.

Prefer new location of pci include files (which have only been in the

2003-08-22T06:42:59+00:00

tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

Pull the pst driver out from under GAINT.

Instead of not grapping a request binfinish(ENOMEM) it if malloc fails.

2003-04-02T11:36:43+00:00

Use bioq_flush() to drain a bio queue with a specific error code.

2003-04-01T15:06:26+00:00

Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include  where this is more appropriate.

Centralize the devstat handling for all GEOM disk device drivers

2003-03-08T08:01:31+00:00

in geom_disk.c.

As a side effect this makes a lot of #include 
lines not needed and some biofinish() calls can be reduced to
biodone() again.

NO_GEOM cleanup:

2003-02-25T08:02:57+00:00

Move to "struct disk *" centric API.
Add NULL check to a malloc(9) return value.
