* | mm: Remove slab destructors from kmem_cache_create().Paul Mundt2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

* | | sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui2007-07-11

What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

* | | sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-11
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

* [SCSI] zfcp: IO stall after deleting and path checker changes after ↵Michael Loehr2007-05-16
| | | | | | | | | | | | | | | | | | | | | | | | reenabling zfcp devices IO stall after deleting and path checker changes after reenabling zfcp device Setting one zfcp device offline using chccwdev in a multipath environment and waiting will lead to IO stall on all paths. After setting the zfcp device back online using chccwdev, the devices with io stall will have a different path checker. Devices corresponding to the deleted units are never freed. This has the effect that 'slave_destroy' is never called and zfcp still thinks that this unit is registered (ZFCP_STATUS_UNIT_REGISTERED is still set). Hence the erp routine is not called correctly and the unit is not enabled properly. Do not delete rport and the sdev. Just set the host to block on 'offline'. Setting host online again will then remove the blocked status and everything is fine again.
