* block: kill swap_io_context()Jens Axboe2008-02-01
| | | | | | | | | | It blindly copies everything in the io_context, including the lock. That doesn't work so well for either lock ordering or lockdep. There seems zero point in swapping io contexts on a request to request merge, so the best point of action is to just remove it. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* as-iosched: fix inconsistent ioc->lock contextJens Axboe2008-02-01
| | | | | | | | | | | Since it's acquired from irq context, all locking must be of the irq safe variant. Most are already inside the queue lock (which already disables interrupts), but the io scheduler rmmod path always has irqs enabled and the put_io_context() path may legally be called with irqs enabled (even if it isn't usually). So fixup those two. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* ide-cd: fix leftover data BUGJens Axboe2008-02-01
| | | | | | | | It's perfectly legal to have data leftovers when a drive signals completion, it happens all the time when a user issues a command with a transfer count that is too large. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* splice: always updated atime in direct spliceJens Axboe2008-02-01
| | | | | | | | | | Andre Majorel <aym-xunil@teaser.fr> points out that if we only updated the atime when we transfer some data, we deviate from the standard of always updating the atime. So change splice to always call file_accessed() even if splice_direct_to_actor() didn't transfer any data. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| * NFS: Switch from intr mount option to TASK_KILLABLEMatthew Wilcox2007-12-06
| | | | | | | | | | | | | | | | | | By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr' mount option.

With the patch attached, I could see that wakeup latencies with FAIR_USER_SCHED are restored to the same level as !FAIR_USER_SCHED. Signed-off-by: Ingo Molnar <mingo@elte.hu>

With ca0102 this card gives no output atall, ca0108 appears to work fine, so it rather looks similar to the EMU1010b/EMU1010 changes.
