headers: remove sched.h from interrupt.h

2009-10-11T18:20:58+00:00

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

libfs: allow error return from simple attributes

2008-02-08T17:22:34+00:00

Sometimes simple attributes might need to return an error, e.g. for
acquiring a mutex interruptibly.  In fact we have that situation in
spufs already which is the original user of the simple attributes.  This
patch merged the temporarily forked attributes in spufs back into the
main ones and allows to return errors.

simplify the stacktrace code

2007-05-08T18:14:58+00:00

Simplify the stacktrace code:

 - remove the unused task argument to save_stack_trace, it's always
   current
 - remove the all_contexts flag, it's alwasy 0

[PATCH] fault injection: split up stacktrace filter Kconfig option

2007-02-21T01:10:14+00:00

There is no prompt for CONFIG_STACKTRACE, so FAULT_INJECTION cannot be
selected without LOCKDEP enabled.  (found by Paolo 'Blaisorblade'
Giarrusso)

In order to fix such broken Kconfig dependency, this patch splits up the
stacktrace filter support for fault injection by new Kconfig option, which
enables to use fault injection on the architecture which doesn't have
general stacktrace support.

Remove stack unwinder for now

2006-12-15T16:47:51+00:00

It has caused more problems than it ever really solved, and is
apparently not getting cleaned up and fixed.  We can put it back when
it's stable and isn't likely to make warning or bug events worse.

In the meantime, enable frame pointers for more readable stack traces.

[PATCH] fault-injection: optimize and simplify should_fail()

2006-12-08T16:29:03+00:00

Trivial optimization and simplification of should_fail().

Do cheaper disqualification tests first (performance gain not quantified).
Simplify logic; eliminate goto.

[PATCH] fault-injection: Clamp debugfs stacktrace-depth to MAX_STACK_TRACE_DEPTH

2006-12-08T16:29:03+00:00

Clamp /debug/fail*/stacktrace-depth to MAX_STACK_TRACE_DEPTH.  Ensures that a
read of /debug/fail*/stacktrace-depth always returns a truthful answer.
