| * ocfs2: Fix rename/extend raceSunil Mushran2007-08-09
| | | | | | | | | | | | | | | | | | | | If one process is extending a file while another is renaming it, there exists a window when rename could flush the old inode's stale i_size to disk. This patch recognizes the fact that rename is only updating the old inode's ctime, so it ensures only that value is flushed to disk.

| | | | | | | | | | | | | | | | ocfs2_max_file_offset() was over-estimating the largest file size for several cases. This wasn't really a problem before, but now that we support sparse files, it needs to be more accurate. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | There's no need to recalculate things via ocfs2_max_file_offset() as we've already done that to fill s_maxbytes, so use that instead. We can also un-export ocfs2_max_file_offset() then. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * ocfs2: Restrict inode changes in ocfs2_update_inode_atime()Mark Fasheh2007-08-09
| | | | | | | | | | | | | | | | | | | | | | ocfs2_update_inode_atime() calls ocfs2_mark_inode_dirty() to push changes from the struct inode into the ocfs2 disk inode. The problem is, ocfs2_mark_inode_dirty() might change other fields, depending on what happened to the struct inode. Since we don't always have locking to serialize changes to other fields (like i_size, etc), just fix things up to only touch the atime field. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

Doublefault is handled by a hardware task, making the check SPIN_BUG_ON(lock->owner == current, lock, "recursion"); fault because it uses the FS register to access the percpu data for current, and that register is zero in the new TSS. (The trace I saw was on 2.6.20 where it was GS, but it looks like this will still happen with FS on 2.6.22.) Initializing FS in the doublefault_tss should fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Averatec 2370 and some other Turion laptop BIOS seems to program the ENABLE_C1E MSR inconsistently between cores. This confuses the lapic use heuristics because when C1E is enabled anywhere it seems to affect the complete chip. Use a global flag instead of a per cpu flag to handle this. If any CPU has C1E enabled disabled lapic use. Thanks to Cal Peake for debugging.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VT is very picky about when it can enter execution. Get all segments setup and get LDT and TR into valid state to allow VT execution under VMware and KVM (untested). This makes the boot decompression run under VT, which makes it several orders of magnitude faster on 64-bit Intel hardware. Before, I was seeing times up to a minute or more to decompress a 1.3MB kernel on a very fast box.

In particular, paravirt_ops does patching in two stages: first it calls paravirt_ops.patch, then it fills any remaining instructions with nop_out(). nop_out calls text_poke() which calls lookup_address() which calls pgd_val() (aka paravirt_ops.pgd_val): that call site is one of the places we patch. If we always do patching as one single call to text_poke(), we only need make sure we're not patching the memcpy in text_poke itself. This means the prototype to paravirt_ops.patch needs to change, to marshal the new code into a buffer rather than patching in place as it does now. It also means all patching goes through text_poke(), which is known to be safe (apply_alternatives is also changed to make a single patch). AK: fix compilation on x86-64 (bad rusty!)

It is based on Yinghai Lu's and Andy Whitcroft's patches (thanks!) with some changes: - introduce pci_scan_bus_with_sysdata() and use it instead of pci_scan_bus() where appropriate. pci_scan_bus_with_sysdata() will allocate the sysdata structure and then call pci_scan_bus(). - always allocate pci_sysdata dynamically. The whole point of this sysdata work is to make it easy to do root-bus specific things (e.g., support PCI domains and IOMMU's). I dislike using a default struct pci_sysdata in some places and a dynamically allocated pci_sysdata elsewhere - the potential for someone indavertantly changing the default structure is too high. - this patch only makes the minimal changes necessary, i.e., the NUMA node is always initialized to -1. Patches to do the right thing with regards to the NUMA node can build on top of this (either add a 'node' parameter to pci_scan_bus_with_sysdata() or just update the node when it becomes known). The patch was compile tested with various configurations (e.g., NUMAQ, VISWS) and run-time tested on i386 and x86-64. Unfortunately none of my machines exhibited the bugs so caveat emptor. Andy, could you please see if this fixes the NUMA issues you've seen? Riku, does this fix "pci=noacpi" on your laptop?

EXPORT_SYMBOL no longer works on symbols that are undefined or defined with static scope. For example, with CONFIG_PROFILE off, I see: kernel/profile.c:206: error: __ksymtab_profile_event_unregister causes a section type conflict kernel/profile.c:205: error: __ksymtab_profile_event_register causes a section type conflict This patch moves the EXPORTs inside the #ifdef CONFIG_PROFILE, so we only try to export symbols that are defined. Also, in kernel/kprobes.c there's an EXPORT_SYMBOL_GPL() for jprobes_return, which if CONFIG_JPROBES is undefined is a static inline and gives the same error. And in drivers/acpi/resources/rsxface.c, there's an ACPI_EXPORT_SYMBOPL() for a static symbol. If it's static, it's not accessible from outside the compilation unit, so should bot be exported. These three changes allow building a zx1_defconfig kernel with gcc 4.2 on IA64.

The problem can be triggered when tcflush() is called when data are being pushed to the line discipline driver by flush_to_ldisc(). flush_to_ldisc() releases tty->buf.lock when calling the line discipline receive_buf function. At that poing tty_buffer_flush() kicks in and sets both tty->buf.head and tty->buf.tail to NULL. When flush_to_ldisc() finishes, it restores tty->buf.head but doesn't touch tty->buf.tail. This corrups the buffer queue, and the next call to tty_buffer_request_room() will allocate a new buffer and overwrite tty->buf.head. The previous buffer is then lost forever without being released. (Thanks to Laurent for the above text, for finding, disgnosing and reporting the bug) - Use tty->flags bits for the flush status. - Wait for the flag to clear again before returning - Fix the doc error noted - Fix flush of empty queue leaving stale flushpending [akpm@linux-foundation.org: cleanup] Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Paul Fulghum <paulkf@microgate.com> Cc: Laurent Pinchart <laurentp@cse-semaphore.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Documentation/sysrq.txt, the description of 'h' says that any key not listed *above* will generate help. That's obviously not true since all the keys listed below 'h' will do what they are described to do, not display help. So change the text so that it says that any key not listed in the table will generate help, which is what really happens.
