Patch from "Theodore Ts'o" <tytso@mit.edu> I recently noticed a bug in ext2/3; newly created inodes which inherit the noatime flag from their containing directory do not respect noatime until the inode is flushed from the inode cache and then re-read later. This is because the code which checks the ext2 no-atime attribute and then sets the S_NOATIME in inode->i_flags is present in ext2_read_inode(), but not in ext2_new_inode(). I fixed this in 2.4, and then found an even worse bug in the 2.5 code; the DIRSYNC flag is completely ignored *except* in the case where a directory is newly created using mkdir and its parent directory has the DIRSYNC flag. S_DIRSYNC doesn't get set in the ext2_new_inode() or the ext2_ioctl() paths (which is used by chattr). This patch centralizes the code which translates the ext2 flags in the raw ext2 inode to the appropriate flag values in inode->i_flags in a single location. This fixes the bug, makes things cleaner, and also removes 30 lines of code and 128 bytes of compiled x86 text in the bargain.

Patch from Oleg Drokin <green@linuxhacker.ru> There is a memleak in e100 driver from intel, both in 2.4 and 2.5 e100_ethtool_gstrings does not free "strings" variable if it cannot copy it to userspace.

Patch from Anders Gustafsson <andersg@0x63.nu> We're getting a division-by-zero in the writeback code during early rootfs population, because writeback has not yet been initialised. Fix that by performing an explicit initialisation rather than relying on initcall ordering.

Patch from Kevin Pedretti <pedretti@ieee.org> The previous fix for unmapping hugetlb regions could still produce incorrect alignments if the munmap request covers multiple VMA's. Fix it by always unmapped the entire hugepage VMA inside the inner loop.

Patch from "Randy.Dunlap" <rddunlap@osdl.org> Reverts the recent alteration of the format of the `mem=' option. This is because `mem=' is interpreted by bootloaders and may not be freely changed. Instead, the new functionality to set specific memory region usages is provided via the new "memmap=" option. The documentation for memmap= is added, and the documentation for mem= is updated.

The recent (untested?) "cleanup" removed a null-pointer test.

As requested by Andrew, this moves the hugetlbfs config option into the Pseudo filesystems section near tmpfs.

Patch from Ivan Kokshaysky This fixes long standing typo ('size' instead of 'r_size') which causes overestimate of the bridge memory ranges calculated in pbus_size_mem(). For example, if we have a device with one 1Mb and one 2Mb memory ranges behind the bridge, calculated size and alignment of the bridge memory window will be 4Mb and 2Mb respectively, while the correct values are 3Mb and 1Mb.

In an attempt to "unuse" pci_do_scan_bus() so it can be eventually killed, make pci_scan_bus_parented() call the new pci_scan_child_bus() and pci_bus_add_devices(). The only remaining callers are the hotplug drivers. Eventually, pci_bus_add_devices() will be removed from this function - it is intended that architectures should call this after they have done any setups and fixups to the scanned bus. It is legal to call pci_bus_add_devices() on a bus which has already had this function called, so architectures could update today.

Kill pcibios_update_resource(), replacing it with pci_update_resource(). pci_update_resource() uses pcibios_resource_to_bus() to convert a resource to a device BAR - the transformation should be exactly the same as the transformation used for the PCI bridges. pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to set the high 32-bits to anything non-zero - currently no architecture attempts to do something different. If anyone cares, please fix; I'm going to reflect current behaviour for the time being. Ivan pointed out the following architectures need to examine their pcibios_update_resource() implementation - they should make sure that this new implementation does the right thing. #warning's have been added where appropriate. ia64 mips mips64 This cset also includes a fix for the problem reported by AKPM where 64-bit arch compilers complain about the resource mask being placed in a u32.

Convert pcibios_fixup_pbus_ranges() into something more generic, namely pcibios_resource_to_bus() - we are really trying to convert resources to something to program into bus registers for bridge windows, and in fact, PCI device BARs. This is necessary since some architectures, namely Alpha, ARM and PARISC have an offset between PCI addressing and host-based addressing, so resources need to be adjusted when read or when written back to the bus. We provide a generic version in asm-generic/pci.h, which most architectures use. This patch finds the following architectures with something to think consider: - ppc, ppc64 adjusts resources for devices, but not buses. This is inconsistent, and leads to improperly programmed windows/BARs. PPC people (Anton) has a replacement PCI resource implementation which should do the right thing.

Patch from Ivan Kokshaysky remove the "parent" or "root" second argument to pcibios_update_resource(). This highlights the following architectures doing something wrong in their implementation: - ia64 - mips it8172 - mips "generic mips boards" - mips64 "generic mips boards" - mips64 IP27

Fix breakage in pci-3 - we scanned all functions if function 0 was not present. This causes some host bridges to lock up when scanning devfn 255 on PPC machines.

This removes/fixes a few whitespaces and removes the MAX_PRIO setting in the init task path which is unnecessary and which might even lead to bugs - MAX_PRIO is outside the valid range and technically the init thread is not an idle thread yet at this point.

This fixes a fundamental (and long-standing) bug in the sleep-average estimator which is the root cause of the "contest process_load" problems reported by Mike Galbraith and Andrew Morton, and which problem is addressed by Mike's patch. The bug is the following: the sleep_time code in activate_task() over-estimates the true sleep time by 0.5 jiffies on average (0.5 msecs on recent 2.5 kernels). Furthermore, for highly context-switch intensive and CPU-intensive workloads it means a constant 1 jiffy over-estimation. This turns the balance of giving and removing ticks and nils the effect of the CPU busy-tick, catapulting the task(s) to highly interactive status - while in reality they are constantly burning CPU time. The fix is to round down sleep_time, not to round it up. This slightly under-estimates the sleep time, but this is not a real problem, any task with a sleep time in the 1 jiffy range will see timekeeping granularity artifacts from various parts of the kernel anyway. We could use rdtsc to estimate the sleep time, but i think that's unnecessary overhead. The fixups in Mike's scheduler patch (which is in -mm8) basically work around this bug. The patch below definitely fixes the contest-load starvation bug, but it remains to be seen what other effects it has on interactivity. In any case, this bug in the estimator is real and if there's any other interactivity problem around then we need to deal with it ontop of this patch. This bug has been in the O(1) scheduler from day 1 on basically, so i'm quite hopeful that a number of interactivity complaints are fixed by this patch.

Changelog since version 1.68 mark II: - merge Mike Anderson's probe() cleanup - num_devs is now "per host" - num_devs is sysfs writeable - add slave_alloc skeleton code So to simulate 154 disks (for example) one might use: # modprobe scsi_debug add_host=11 num_devs=14 With max_luns at its default value of 2, 14 is the maximum number of devices per host scsi_debug will respond to (i.e. 7 targets, each with 2 lus). Documentation updated at: http://www.torque.net/sg/sdebug25.html

make's line continuation without explicit backslashes is a mystery to me, and in this case, vmlinux got linked, but the linker command was not written to the screen. Works again now.

This is Robert PJ Day's patch that updates the filesystems config menu. It had become a bit ad hoc (jumbled:) and this patch attempts to arrange it more logically.

This adds the support for the menuconfig to the front ends. qconf also has now an ".." entry to make it more obvious how to get to a parent menu.

Roman Zippel authored
This adds the support for the menuconfig keyword, which allows to define a config symbol and a submenu with a single step, e.g. instead of menu "SCSI device support" config SCSI tristate "SCSI device support" this is now enough: menuconfig SCSI tristate "SCSI device support"

A menu entry was possibly inserted to high in the menu hierarchie if the previous entry was a derived config symbol.

This restores the old config behaviour for dependencies on 'm', such entries are only activ if CONFIG_MODULES is enabled as well.
