* [PATCH] reiser4: vfs: add truncate_inode_pages_range()Hans Reiser2006-01-06
| | | | | | | | | | | | | | | | This patch makes truncate_inode_pages_range from truncate_inode_pages. truncate_inode_pages became a one-liner call to truncate_inode_pages_range. Reiser4 needs truncate_inode_pages_ranges because it tries to keep correspondence between existences of metadata pointing to data pages and pages to which those metadata point to. So, when metadata of certain part of file is removed from filesystem tree, only pages of corresponding range are to be truncated.

* [PATCH] nbd: fix TX/RX race conditionHerbert Xu2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Janos Haar of First NetCenter Bt. reported numerous crashes involving the NBD driver. With his help, this was tracked down to bogus bio vectors which in turn was the result of a race condition between the receive/transmit routines in the NBD driver. The bug manifests itself like this: CPU0 CPU1 do_nbd_request add req to queuelist nbd_send_request send req head for each bio kmap send nbd_read_stat nbd_find_request nbd_end_request kunmap When CPU1 finishes nbd_end_request, the request and all its associated bio's are freed. So when CPU0 calls kunmap whose argument is derived from the last bio, it may crash. Under normal circumstances, the race occurs only on the last bio. However, if an error is encountered on the remote NBD server (such as an incorrect magic number in the request), or if there were a bug in the server, it is possible for the nbd_end_request to occur any time after the request's addition to the queuelist. The following patch fixes this problem by making sure that requests are not added to the queuelist until after they have been completed transmission. In order for the receiving side to be ready for responses involving requests still being transmitted, the patch introduces the concept of the active request. When a response matches the current active request, its processing is delayed until after the tranmission has come to a stop. This has been tested by Janos and it has been successful in curing this race condition. From: Herbert Xu <herbert@gondor.apana.org.au> Here is an updated patch which removes the active_req wait in nbd_clear_queue and the associated memory barrier. I've also clarified this in the comment.

| * [PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATEZach Brown2006-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | readpage(), prepare_write(), and commit_write() callers are updated to understand the special return code AOP_TRUNCATED_PAGE in the style of writepage() and WRITEPAGE_ACTIVATE. AOP_TRUNCATED_PAGE tells the caller that the callee has unlocked the page and that the operation should be tried again with a new page. OCFS2 uses this to detect and work around a lock inversion in its aop methods. There should be no change in behaviour for methods that don't return AOP_TRUNCATED_PAGE. WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are made enums so that kerneldoc can be used to document their semantics. Signed-off-by: Zach Brown <zach.brown@oracle.com>

| * | [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski2006-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.

Only during early boot and in initramfs, /sbin/hotplug is needed. So merge the two functions and provide only one interface without all the options. The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core. The uevents should only be used for driver core related requests to userspace now. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
