* eCryptfs: delay writing 0's after llseek until writeMichael Halcrow2007-05-23
| | | | | | | | | | | | | | | | | Delay writing 0's out in eCryptfs after a seek past the end of the file until data is actually written. http://www.opengroup.org/onlinepubs/009695399/functions/lseek.html ``The lseek() function shall not, by itself, extend the size of a file.''

* md: fix bug with linear hot-add and elsewhereNeilBrown2007-05-23
| | | | | | | | | | | | | | Adding a drive to a linear array seems to have stopped working, due to changes elsewhere in md, and insufficient ongoing testing...

* md: avoid overflow in raid0 calculation with large componentsNeilBrown2007-05-23
| | | | | | | | | | | | | | | | | | | If a raid0 has a component device larger than 4TB, and is accessed on a 32bit machines, then as 'chunk' is unsigned long, chunk << chunksize_bits can overflow (this can be as high as the size of the device in KB). chunk itself will not overflow (without triggering a BUG). So change 'chunk' to be 'sector_t, and get rid of the 'BUG' as it becomes impossible to hit.

* signalfd: retrieve multiple signals with one read() callDavi Arnaut2007-05-23
| | | | | | | | | | | | | | | | | Gathering signals in bulk enables server applications to drain a signal queue (almost full of realtime signals) more efficiently by reducing the syscall and file look-up overhead.

* simplify cleanup_workqueue_thread()Oleg Nesterov2007-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | cleanup_workqueue_thread() and cwq_should_stop() are overcomplicated. Convert the code to use kthread_should_stop/kthread_stop as was suggested by Gautham and Srivatsa. In particular this patch removes the (unlikely) busy-wait loop from the exit path, it was a temporary and ugly kludge (if not a bug). Note: the current code was designed to solve another old problem: work->func can't share locks with hotplug callbacks. I think this could be done, see http://marc.info/?l=linux-kernel&m=116905366428633 but this needs some more complications to preserve CPU affinity of cwq->thread during cpu_up(). A freezer-based hotplug looks more appealing.

* SLUB Debug: fix check for super sized slabs (>512k 64bit, >256k 32bit)Christoph Lameter2007-05-23
| | | | | | | | | | | | | | | | The check for super sized slabs where we can no longer move the free pointer behind the object for debugging purposes etc is accessing a field that is not setup yet. We must use objsize here since the size of the slab has not been determined yet. The effect of this is that a global slab shrink via "slabinfo -s" will show errors about offsets being wrong if booted with slub_debug. Potentially there are other troubles with huge slabs under slub_debug because the calculated free pointer offset is truncated.

* recalc_sigpending_tsk fixesRoland McGrath2007-05-23
| | | | | | | | | | | | | | | | | | | Steve Hawkes discovered a problem where recalc_sigpending_tsk was called in do_sigaction but no signal_wake_up call was made, preventing later signals from waking up blocked threads with TIF_SIGPENDING already set. In fact, the few other calls to recalc_sigpending_tsk outside the signals code are also subject to this problem in other race conditions. This change makes recalc_sigpending_tsk private to the signals code. It changes the outside calls, as well as do_sigaction, to use the new recalc_sigpending_and_wake instead.

* Ignore bogus ACPI info for offline CPUsThomas Gleixner2007-05-23
| | | | | | | | | | | | | | | Booting a SMP kernel with maxcpus=1 on a SMP system leads to a hard hang, because ACPI ignores the maxcpus setting and sends timer broadcast info for the offline CPUs. This results in a stuck for ever call to smp_call_function_single() on an offline CPU. Ignore the bogus information and print a kernel error to remind ACPI folks to fix it.
