* [PATCH] Add dm-snapshot tutorial in DocumentationPaolo 'Blaisorblade' Giarrusso2005-09-221-0/+73

* [PATCH] NFS: fix client oops when debugging is onNick Wilson2005-09-221-3/+2
| | | | | | | | | | | | | | nfs_readpage_release() causes an oops while accessing a file with NFS debugging turned on (echo 32767 > /proc/sys/sunrpc/nfs_debug) and a kernel built with CONFIG_DEBUG_SLAB. This patch moves the debugging statement above nfs_release_request() to avoid accessing freed memory.

* [PATCH] Fix bd_claim() error code.Rob Landley2005-09-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Problem: In some circumstances, bd_claim() is returning the wrong error code. If we try to swapon an unused block device that isn't swap formatted, we get -EINVAL. But if that same block device is already mounted, we instead get -EBUSY, even though it still isn't a valid swap device. This issue came up on the busybox list trying to get the error message from "swapon -a" right. If a swap device is already enabled, we get -EBUSY, and we shouldn't report this as an error. But we can't distinguish the two -EBUSY conditions, which are very different errors. In the code, bd_claim() returns either 0 or -EBUSY, but in this case busy means "somebody other than sys_swapon has already claimed this", and _that_ means this block device can't be a valid swap device. So return -EINVAL there. Signed-off-by: Rob Landley <rob@landley.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] uml: replace printk with "stack-friendly" printf - to report console ↵Paolo 'Blaisorblade' Giarrusso2005-09-221-16/+42
| | | | | | | | | | | | | | | | | failure User get *a lot* confused when consoles don't work but we don't report anything. And, as reported in the comment, using printk to report "your console doesn't work" isn't likely to go that far. Fix the problem on the base of this: stack consumption by host printf(). Use kernel sprintf() and os_write_file, using a wild guess that one page will be enough for the message, to preallocate the buffer with kmalloc().

* [PATCH] uml: use GFP_ATOMIC for allocations under spinlocks.Paolo 'Blaisorblade' Giarrusso2005-09-222-2/+2
| | | | | | | | | | | | | | | | | setup_initial_poll is only called with sigio_lock() held, so use appropriate allocation. Also, parse_chan() can also be called when holding a spinlock (see line_open() -> parse_chan_pair()). I have sporadic problems (spinlock taken twice, with spinlock debugging on UP) which could be caused by a sequence like "take spinlock, alloc and go to sleep, take again the spinlock in the other thread".

* [PATCH] uml: avoid fixing faults while atomicPaolo 'Blaisorblade' Giarrusso2005-09-221-0/+7
| | | | | | | | | | | | | | | | | | Following i386, we should maybe refuse trying to fault in pages when we're doing atomic operations, because to handle the fault we could need to take already taken spinlocks. Also, if we're doing an atomic operation (in the sense of in_atomic()) we're surely in kernel mode and we're surely going to handle adequately the failed fault, so it's safe to behave this way. Currently, on UML SMP is rarely used, and we don't support PREEMPT, so this is unlikely to create problems right now, but it might in the future.

| | | | | | | | | | | | | | | Things are breaking horribly with sysrq called in interrupt context. I want to try to fix it, but probably this is simpler. To tell the truth, sysrq is normally run in interrupt context, so there shouldn't be any problem. There's also a warning from the fault handler because it's run in atomic context (I have a patch for that, only I deferred it). This is why I'm doing this.

* [PATCH] uml: fix hang in TT mode on faultPaolo 'Blaisorblade' Giarrusso2005-09-222-3/+19
| | | | | | | | | | | | | | | | | | | | The current code doesn't handle well general protection faults on the host - it thinks that cr2 is always the address of a page fault. While actually, on general protection faults, that address is not accessible, so we'd better assume we couldn't satisfy the fault. Currently instead we think we've fixed it, so we go back, retry the instruction and fault again endlessly. This leads to the kernel hanging when doing copy_from_user(dest, -1, ...) in TT mode, since reading *(-1) causes a GFP, and we don't support kernel preemption.

| | | | | | | | | | | | | | | | I had an issue on ia64 where I got a bug in kernel/workqueue because kzalloc returned a NULL pointer due to the task structure getting too big for the slab allocator. Usually these cases are caught by the kmalloc macro in include/linux/slab.h. Compilation will fail if a too big value is passed to kmalloc. However, kzalloc uses __kmalloc which has no check for that. This patch makes __kmalloc bug if a too large entity is requested.

| | | | | | | | | | | | | | | | | | | The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.

* [PATCH] slab: fix handling of pages from foreign NUMA nodesChristoph Lameter2005-09-221-19/+19
| | | | | | | | | | | | | | | | | | The numa slab allocator may allocate pages from foreign nodes onto the lists for a particular node if a node runs out of memory. Inspecting the slab->nodeid field will not reflect that the page is now in use for the slabs of another node. This patch fixes that issue by adding a node field to free_block so that the caller can indicate which node currently uses a slab. Also removes the check for the current node from kmalloc_cache_node since the process may shift later to another node which may lead to an allocation on another node than intended.

| | | | | | | | | | | | | | | | | | | | Wire the MCA/INIT handler stacks into DTR[2] and track them in IA64_KR(CURRENT_STACK). This gives the MCA/INIT handler stacks the same TLB status as normal kernel stacks. Reload the old CURRENT_STACK data on return from OS to SAL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sd driver now uses scsi_execute_req() for almost everything. scsi_execute_req() converts requests into scatterlists. Fix the HP SCSI disk simulator to understand scatterlists for more commands. Without this patch the current kernel will not boot on the simulator (the disks are always detected as having no sectors, and so cannot be mounted).
