[PATCH] timer stats: speedups

2007-06-11T18:36:48Z

Make timer-stats have almost zero overhead when enabled in the config but not used. (this way distros can enable it more easily) Also update the documentation about overhead of timer_stats - it was written for the first version which had a global lock and a linear list walk based lookup ;-) Andrew says: And this. Not a bugfix, but trivial and obvious and apparently some distros don't want to enable timer_stats because of the performance issue, but powertop uses timer_stats. Ingo replies: seconded. I have tested this with and without CONFIG_TIMER_STATS, with and without timer_stats collection activated.

[PATCH] ppp: Fix ppp_deflate issues with recent zlib_inflate changes

2007-05-23T21:32:43Z

The last zlib_inflate update broke certain corner cases for ppp_deflate decompression handling. This patch fixes some logic to make things work properly again. Users other than ppp_deflate (the only Z_PACKET_FLUSH user) should be unaffected. Fixes bug 8405 (confirmed by Stefan) Signed-off-by: Richard Purdie Cc: Stefan Wenk Signed-off-by: Andrew Morton Signed-off-by: Chris Wright

kobject: new_device->kref wasn't putted after error in kobject_move()

2007-03-09T23:32:58Z

If error happen we jump to "out" label, in this case new_device not yet became the parent but it wasn't putted. Signed-off-by: Monakhov Dmitriy Signed-off-by: Greg Kroah-Hartman

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

2007-02-21T01:10:14Z

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.

[PATCH] Convert highest_possible_processor_id to nr_cpu_ids

2007-02-21T01:10:13Z

We frequently need the maximum number of possible processors in order to allocate arrays for all processors. So far this was done using highest_possible_processor_id(). However, we do need the number of processors not the highest id. Moreover the number was so far dynamically calculated on each invokation. The number of possible processors does not change when the system is running. We can therefore calculate that number once.
