kernel as a pseudo-device. The changes were:
- #ifdef DEBUG -> #ifdef VINUMDEBUG
- opt_vinum.h for holding above config variable
- Fixing up a few stray problems where DEBUG wasn't optional.
- config.c -> vinumconfig.c (there's already a config.o)
- Other *.c -> vinum*.c (wasn't strictly necessary, but done in case we end
up with something else conflicting later on and we might have to have yet
more repository copies of files).
- include file paths fixups.. (ie: get them all from the kernel tree
instead of partly from the kernel and partly from /usr/include/machine)
I've spoken with Greg about this.. I hope this doesn't mess him around
too much..
config_drive:
Catch an instance of anonymous drives. Doubtless many remain.
interrupt.c:
complete_rqe:
Call logrq to log iodone events if DEBUG_LASTREQS is set.
Call set_sd_state with setstate_noupdate to avoid buffered I/O out
of interrupt context.
Use define DEBUG_RESID instead of constant.
memory.c:
Remove dead expandrq() function
Malloc:
Remove directory component of file names in malloc table.
Add function vinum_rqinfo (part of the request tracing stuff).
request.c:
Add function logrq (part of the request tracing stuff).
vinumstrategy:
Check whether config needs to be written to disk, do it if so.
This is a stopgap until the Vinum daemon (bacchusd? oenologistd?)
is written.
If DEBUG_LASTREQS is set, call logrq to log user buffer headers.
launch_requests:
Correct format of debug output to console.
If DEBUG_LASTREQS is set, call logrq to log request elements.
request.h:
Add definitions for request trace.
state.c:
set_sd_state:
Check flags for setstate_noupdate. If set, don't write the config
to disk, just set global VF_DIRTYCONFIG flag. This is part of the
kludge to avoid writing config from an interrupt context.
vinumext.h:
Add declaration for vinum_rqinfo, put inside #ifdef DEBUG
Remove dead macro expandrq
vinumio.h:
Increase maximum ioctl reply length to 4 kB if DEBUG is set.
Define VINUM_RQINFO ioctl if DEBUG is set.
vinumioctl.c:
vinumioctl:
Change implementation of VINUM_DEBUG ioctl: use a debug flag
(DEBUG_REMOTEGDB) to decide whether to go into remote debugging or
not.
Implement VINUM_RQINFO.
vinumkw.h:
Define kw_info even when not debugging.
vinumvar.h:
Define VF_DIRTYCONFIG
Add pointers to request info to vinum_info if DEBUG is set.
Define setstate_noupdate
Define additional debug bits DEBUG_RESID, DEBUG_LASTREQS and
DEBUG_REMOTEGDB.
