* loop: preallocate eight loop devicesKen Chen2007-06-08
| | | | | | | | | | | | The kernel on-demand loop device instantiation breaks several user space tools as the tools are not ready to cope with the "on-demand feature".

* cciss: Fix pci_driver.shutdown while device is still activeGerald Britton2007-05-19
| | | | | | | | | | | | | | | | | 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.

Speaking of which, we probably want to s/lock/pin/ in drivers/base/map.c to avoid such brainos again. And yes, this stuff needs clear documentation.

* | fs: convert core functions to zero_user_pageNate Diller2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* remove artificial software max_loop limitKen Chen2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] cciss: fix for 2TB supportMike Miller (OS Dev)2007-03-06
| | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* | [PATCH] disable init/initramfs.cJean-Paul Saman2007-02-11
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file init/initramfs.c is always compiled and linked in the kernel vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the system isn't using any form of an initramfs or initrd. In this situation the code is only used to unpack a (static) default initial rootfilesystem. The current init/initramfs.c code. usr/initramfs_data.o compiles to a size of ~15 kbytes. Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel code size with ~60 Kbytes. This patch avoids compiling in the code and data for initramfs support if CONFIG_BLK_DEV_INITRD is not defined. Instead of the initramfs code and data it uses a small routine in init/noinitramfs.c to setup an initial static default environment for mounting a rootfilesystem later on in the kernel initialisation process. The new code is: 164 bytes of size. The patch is separated in two parts: 1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set 2) changing all plaforms vmlinux.lds.S files to not reserve an area of PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.

* [PATCH] Fix BUG at drivers/scsi/scsi_lib.c:1118 caused by "pktsetup dvd ↵Christoph Hellwig2007-01-06
| | | | | | | | | | | | | | | | | | | | | /dev/sr0" Fix http://bugzilla.kernel.org/show_bug.cgi?id=7667 This is because the packet driver tries to send down read/write BLOCK_PC commands that don't use a bio and do not use sg lists. The right fix is to replace all the packet_command stuff in the packet driver by scsi_execute() which needs to be lifted from scsi code to the block code for that. Fix the bug for now. It's not the full way to a generic execute block pc infrastcuture but fixes the bug for the time being.

* [PATCH] fix aoe without scatter-gather [Bug 7662]Ed L. Cashin2006-12-22
| | | | | | | | | | | | | | | | | | | | Fix a bug that only appears when AoE goes over a network card that does not support scatter-gather. The headers in the linear part of the skb appeared to be larger than they really were, resulting in data that was offset by 24 bytes. This patch eliminates the offset data on cards that don't support scatter-gather or have had scatter-gather turned off. There remains an unrelated issue that I'll address in a separate email.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a stupid bug. Sometime during the 2tb enhancement I ended up replacing the macros XFER_READ and XFER_WRITE with h->cciss_read and h->cciss_write respectively. It seemed to work somehow at least on x86_64 and ia64. I don't know how. But people started complaining about command timeouts on older controllers like the 64xx series and only on ia32. This resolves the issue reproduced in our lab. Please consider this for inclusion. Thanks, mikem Signed-off-by: Mike Miller <mike.miller@hp.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
