316aed030e Add handling for cancelled events in the g_call_me() methods. 2003-04-02 21:10:04 +00:00
Poul-Henning Kamp
afcbcfaed0 Change events to have an array of "void *" references, and give the 
event posting functions varargs to fill these.

Attribute g_call_me() to appropriate g_geom's where necessary.

Add a flag argument to g_call_me() methods which will be used to signal
cancellation of events in the future.

This commit should be a no-op.

c7e1925c7c Properly handle races between open/close and orphan. 
KASSERT the race between close and strategy, it is an error in the upper
echelons if this happens,

Add XXX: comment explaining why the ioctl/orphan race is not closed.

891619a66d Use bioq_flush() to drain a bio queue with a specific error code. 
Retain the mistake of not updating the devstat API for now.

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

#include <geom/geom_disk.h> where this is more appropriate.

afa2a5aab7 Remove some debugging in the new OAM[*] and add a debug flag for other 
parts of it.

[*] I've been asked what "OAM" means:  It's an acronym used in the
telecom industry, "Operations And Maintenance", and there it covers
anything from a single unlabeled led on the frontpanel the the full
nightmare of CMIP for SS7.

d49d7ca591 Turn /dev/geom.ctl from a GEOM class into a plain character device driver 
instead, it will never see a disk-I/O transaction, so this is a lot simpler.

Poul-Henning Kamp
b4b138c27f Including <sys/stdint.h> is (almost?) universally only to be able to use 
%j in printfs, so put a newsted include in <sys/systm.h> where the printf
prototype lives and save everybody else the trouble.

e582990901 If we run out of consumers while orphaning them, and the provider's geom 
is withering, destroy the provider when done.

This was exposed by the recent change to geom_dev's orphaning logic.

c6ae9b5fd2 Don't abuse the statistics counters for detecting if we have outstanding 
I/O requests, instead use the new dedicated fields in the consumer and
provider to track this.

0e082fcca2 Add u_int nstart, nend counters to consumer and providers so we will not 
have to examine the stats structure to tell if we have outstanding I/O
requests.

Making them u_int improves the chance of atomic updates to them,
but risks roll-over.  Since the only interesting property is if
they are equal or not, this is not an issue.

df6c9fe955 When a DEV class consumer is orphan'ed we need to wait for all the 
outstanding requests to return before we unravel the mesh.

It is very important that the stuff below us plays nice and don't
overlook a couple of outstanding bio's, because until they remember
the geom event thread is blocked.  At an expense in code here this
could be made more robust, but I actually _want_ a robust failure
in this case so any offending drivers can be fixed.

Poul-Henning Kamp
60794e0478 Centralize the devstat handling for all GEOM disk device drivers 
in geom_disk.c.

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