2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
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.)

2007-07-10pipe: change the ->pin() operation to ->confirm()Jens Axboe
The name 'pin' was badly chosen, it doesn't pin a pipe buffer in the most commonly used sense in the kernel. So change the name to 'confirm', after debating this issue with Hugh Dickins a bit. A good return from ->confirm() means that the buffer is really there, and that the contents are good. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-05-18cciss: Fix pci_driver.shutdown while device is still activeGerald Britton
Fix an Oops in the cciss driver caused by system shutdown while a filesystem on a cciss device is still active. The cciss_remove_one function only properly removes the device if the device has been cleanly released by its users, which is not the case when the pci_driver.shutdown method is called. This patch adds a new cciss_shutdown function to better match the pattern used by various SCSI drivers: deactivate device interrupts and flush caches. It also alters the cciss_remove_one function to match and readds the __devexit annotation that was removed when cciss_remove_one was serving as the pci_driver.shutdown method.

2007-05-09fs: convert core functions to zero_user_pageNate Diller
It's very common for file systems to need to zero part or all of a page, the simplist way is just to use kmap_atomic() and memset(). There's actually a library function in include/linux/highmem.h that does exactly that, but it's confusingly named memclear_highpage_flush(), which is descriptive of *how* it does the work rather than what the *purpose* is. So this patchset renames the function to zero_user_page(), and calls it from the various places that currently open code it. This first patch introduces the new function call, and converts all the core kernel callsites, both the open-coded ones and the old memclear_highpage_flush() ones. Following this patch is a series of conversions for each file system individually, per AKPM, and finally a patch deprecating the old call. The diffstat below shows the entire patchset.

Set rq->errors more correctly in cciss driver. Previously we had set it synonymously with the meaning of the last parameter of end_that_last_request and complete_buffers (the "uptodate" parameter) and had gotten away with it for all this time because nobody ever looked at rq->errors.

2007-05-08remove artificial software max_loop limitKen Chen
Remove artificial maximum 256 loop device that can be created due to a legacy device number limit. Searching through lkml archive, there are several instances where users complained about the artificial limit that the loop driver impose. There is no reason to have such limit. This patch rid the limit entirely and make loop device and associated block queue instantiation on demand. With on-demand instantiation, it also gives the benefit of not wasting memory if these devices are not in use (compare to current implementation that always create 8 loop devices), a net improvement in both areas. This version is both tested with creation of large number of loop devices and is compatible with existing losetup/mount user land tools.

initramfs ended up depending on BLOCK: INITRAMFS_SOURCE <-- BLK_DEV_INITRD <-- BLOCK This inhibits use of customized-initramfs-over-ramfs without block layer (ramfs would still be enabled), useful in embedded applications. Move BLK_DEV_INITRD out of 'drivers/block/Kconfig' and into 'init/Kconfig', make it unconditional.

2007-03-06[PATCH] cciss: add struct pci_driver shutdown support (replaces reboot notifier)Mike Miller (OS Dev)
This patch adds support for the struct pci_driver shutdown method to cciss. We require notification of an impending reboot or shutdown so that we can flush the battery backed write cache (BBWC) on the Smart Array controller.

2007-03-06[PATCH] cciss: fix for 2TB supportMike Miller (OS Dev)
This patch changes the way we determine if a logical volume is larger than 2TB. The original test looked for a total_size of 0. Originally we added 1 to the total_size. That would make our read_capacity return size 0 for >2TB lv's. We assumed that we could not have a lv size of 0 so it seemed OK until we were in a clustered system. The backup node would see a size of 0 due to the reservation on the drive. That caused the driver to switch to 16-byte CDB's which are not supported on older controllers. After that everything was broken. It may seem petty but I don't see the value in trying to determine if the LBA is beyond the 2TB boundary. That's why when we switch we use 16-byte CDB's for all read/write operations. Please consider this for inclusion.

2007-02-20[PATCH] Fix build errors if bitop functions are do {} while macrosRalf Baechle
If one of clear_bit, change_bit or set_bit is defined as a do { } while (0) function usage of these functions in parenthesis like (foo_bit(23, &var)) while be expaned to something like (do { ... } while (0)}). resulting in a build error. This patch removes the useless parenthesis.
