If the new code is substantial, addition of subsystem-specific fault
injection might be appropriate.

lots of noise, but is good for finding bugs like "warning: comparison

=========
The Linux version of the 9p server is now maintained under the npfs project
on sourceforge (http://sourceforge.net/projects/npfs).
Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)
as the 9p server. You can start a 9p server under Inferno by issuing the
following command:
; styxlisten -A tcp!*!564 export '#U*'
The -A specifies an unauthenticated export. The 564 is the port # (you may
have to choose a higher port number if running as a normal user). The '#U*'
specifies exporting the root of the Linux name space. You may specify a
subset of the namespace by extending the path: '#U*'/tmp would just export
/tmp. For more information, see the Inferno manual pages covering styxlisten
and export.
A Linux version of the 9p server is now maintained under the npfs project
on sourceforge (http://sourceforge.net/projects/npfs). There is also a
more stable single-threaded version of the server (named spfs) available from
the same CVS repository.
There are user and developer mailing lists available through the v9fs project
on sourceforge (http://sourceforge.net/projects/v9fs).

- No specific options are required to create a dump-capture kernel
for ia64, other than those specified in the arch idependent section
above. This means that it is possible to use the system kernel
as a dump-capture kernel if desired.
The crashkernel region can be automatically placed by the system
kernel at run time. This is done by specifying the base address as 0,
or omitting it all together.
crashkernel=256M@0

The Magic SysRQ system works by registering key operations against a key op
lookup table, which is defined in 'drivers/char/sysrq.c'. This key table has
a number of operations registered into it at compile time, but is mutable,
and 4 functions are exported for interface to it: __sysrq_lock_table,
__sysrq_unlock_table, __sysrq_get_key_op, and __sysrq_put_key_op. The
functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined
in the header itself, and the REGISTER and UNREGISTER macros are built from
these. More complex (and dangerous!) manipulations of the table are possible
using these functions, but you must be careful to always lock the table before
you read or write from it, and to unlock it again when you are done. (And of
course, to never ever leave an invalid pointer in the table). Null pointers in
the table are always safe :)
and 2 functions are exported for interface to it:
register_sysrq_key and unregister_sysrq_key.
Of course, never ever leave an invalid pointer in the table. I.e., when
your module that called register_sysrq_key() exits, it must call
unregister_sysrq_key() to clean up the sysrq key table entry that it used.
Null pointers in the table are always safe. :)
If for some reason you feel the need to call the handle_sysrq function from

SMTC pseudo-interrupts between TCs are deferred and queued
if the target TC is interrupt-inhibited (IXMT). In the first
SMTC prototypes, these queued IPIs were serviced on return
to user mode, or on entry into the kernel idle loop. The
INSTANT_REPLAY option dispatches them as part of local_irq_restore()
processing, which adds runtime overhead (hence the option to turn
it off), but ensures that IPIs are handled promptly even under
heavy I/O interrupt load.
