2007-12-18sched: mark rwsem functions as __sched for wchan/profilingLivio Soares
This following commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fdf8cb0909b531f9ae8f9b9d7e4eb35ba3505f07 un-inlined a low-level rwsem function, but did not mark it as __sched. The result is that it now shows up as thread wchan (which also affects /proc/profile stats). The following simple patch fixes this by properly marking rwsem_down_failed_common() as a __sched function. Also in this patch, which is up for discussion, marks down_read() and down_write() proper as __sched. For profiling, it is pretty much useless to know that a semaphore is beig help - it is necessary to know _which_ one. By going up another frame on the stack, the information becomes much more useful. In summary, the below change to lib/rwsem.c should be applied; the changes to kernel/rwsem.c could be applied if other kernel hackers agree with my proposal that down_read()/down_write() in the profile is not enough.

2007-12-18sched: fix crash on ia64, introduce task_current()Dmitry Adamushko
Some services (e.g. sched_setscheduler(), rt_mutex_setprio() and sched_move_task()) must handle a given task differently in case it's the 'rq->curr' task on its run-queue. The task_running() interface is not suitable for determining such tasks for platforms with one of the following options: #define __ARCH_WANT_UNLOCKED_CTXSW #define __ARCH_WANT_INTERRUPTS_ON_CTXSW Due to the fact that it makes use of 'p->oncpu == 1' as a criterion but such a task is not necessarily 'rq->curr'.

On last close of a file we purge blocks beyond eof. The same code is used when we truncate the file size down. In this case we need to wait for any pending I/Os for dirty pages beyond the new eof. For the last close case we are not changing the file size and therefore do not need to wait for any I/Os to complete. This fixes a performance bottleneck where writes into the page cache and cache flushes can become mutually exclusive.

2007-12-17hugetlb: introduce nr_overcommit_hugepages sysctlNishanth Aravamudan
hugetlb: introduce nr_overcommit_hugepages sysctl While examining the code to support /proc/sys/vm/hugetlb_dynamic_pool, I became convinced that having a boolean sysctl was insufficient: 1) To support per-node control of hugepages, I have previously submitted patches to add a sysfs attribute related to nr_hugepages. However, with a boolean global value and per-mount quota enforcement constraining the dynamic pool, adding corresponding control of the dynamic pool on a per-node basis seems inconsistent to me. 2) Administration of the hugetlb dynamic pool with multiple hugetlbfs mount points is, arguably, more arduous than it needs to be. Each quota would need to be set separately, and the sum would need to be monitored. To ease the administration, and to help make the way for per-node control of the static & dynamic hugepage pool, I added a separate sysctl, nr_overcommit_hugepages. This value serves as a high watermark for the overall hugepage pool, while nr_hugepages serves as a low watermark. The boolean sysctl can then be removed, as the condition nr_overcommit_hugepages > 0 indicates the same administrative setting as hugetlb_dynamic_pool == 1 Quotas still serve as local enforcement of the size of the pool on a per-mount basis. A few caveats: 1) There is a race whereby the global surplus huge page counter is incremented before a hugepage has allocated. Another process could then try grow the pool, and fail to convert a surplus huge page to a normal huge page and instead allocate a fresh huge page. I believe this is benign, as no memory is leaked (the actual pages are still tracked correctly) and the counters won't go out of sync. 2) Shrinking the static pool while a surplus is in effect will allow the number of surplus huge pages to exceed the overcommit value. As long as this condition holds, however, no more surplus huge pages will be allowed on the system until one of the two sysctls are increased sufficiently, or the surplus huge pages go out of use and are freed. Successfully tested on x86_64 with the current libhugetlbfs snapshot, modified to use the new sysctl.

ecryptfs in 2.6.24-rc3 wasn't surviving fsx for me at all, dying after 4 ops. Generally, encountering problems with stale data and improperly zeroed pages. An extending truncate + write for example would expose stale data. With the changes below I got to a million ops and beyond with all mmap ops disabled - mmap still needs work. (A version of this patch on a RHEL5 kernel ran for over 110 million fsx ops) I added a few comments as well, to the best of my understanding as I read through the code.

2007-12-17fix bloat-o-meter for ppc64Nathan Lynch
bloat-o-meter assumes that a '.' anywhere in a symbol's name means that it is static and prepends 'static.' to the first part of the symbol name, discarding the portion of the name that follows the '.'. However, the names of function entry points begin with '.' in the ppc64 ABI. This causes all function text size changes to be accounted to a single 'static.' entry in the output when comparing ppc64 kernels. Change getsizes() to ignore the first character of the symbol name when searching for '.'.

2007-12-17mm: fix page allocation for larger I/O segmentsMel Gorman
In some cases the IO subsystem is able to merge requests if the pages are adjacent in physical memory. This was achieved in the allocator by having expand() return pages in physically contiguous order in situations were a large buddy was split. However, list-based anti-fragmentation changed the order pages were returned in to avoid searching in buffered_rmqueue() for a page of the appropriate migrate type. This patch restores behaviour of rmqueue_bulk() preserving the physical order of pages returned by the allocator without incurring increased search costs for anti-fragmentation.

SPARSEMEM_VMEMMAP needs to be a selectable config option to support building the kernel both with and without sparsemem vmemmap support. This selection is desirable for platforms which could be configured one way for platform specific builds and the other for multi-platform builds.

2007-12-17ecryptfs: initialize new auth_tokens before teardownEric Sandeen
ecryptfs_destroy_mount_crypt_stat() checks whether each auth_tok->global_auth_tok_key is nonzero and if so puts that key. However, in some early mount error paths nothing has initialized the pointer, and we try to key_put() garbage. Running the bad cipher tests in the testsuite exposes this, and it's happy with the following change.

2007-12-17alpha: strncpy/strncat fixesIvan Kokshaysky
First of all, thanks to Bob Tracy <rct@frus.com> and Michael Cree <mcree@orcon.net.nz> for testing. Especially to Bob, as he has done titanic multi-day git-bisect work that finally helped to reproduce and nail down the bug (http://bugzilla.kernel.org/show_bug.cgi?id=9457). [ev6-]stxncpy.S: it's t12, not t2 register that is supposed to contain the last byte offset upon return. As a result of wrong register use (which was my fault back in 2003, IIRC), under some circumstances extra terminating zero bytes were added to destination string. This particularly led to incorrect DEVPATH strings generated in uevent and therefore to udev problems. strncpy.S: unrelated bug I found while testing the above fix - destination is not properly zero-padded then a byte count exceeds source length. Actually this is addition to strncpy fix from last year.

2007-12-17uml: stop gdb from deleting breakpoints when running UMLStanislaw Gruszka
Sometimes when UML is debugged gdb miss breakpoints. When process traced by gdb do fork, debugger remove breakpoints from child address space. There is possibility to trace more than one fork, but this not work with UML, I guess (only guess) there is a deadlock - gdb waits for UML and UML waits for gdb. When clone() is called with SIGCHLD and CLONE_VM flags, gdb see this as PTRACE_EVENT_FORK not as PTRACE_EVENT_CLONE and remove breakpoints from child and at the same time from traced process, because either have the same address space. Maybe it is possible to do fix in gdb, but I'm not sure if there is easy way to find out if traced and child processes share memory. So I do fix for UML, it simply do not call clone() with both SIGCHLD and CLONE_VM flags together. Additionally __WALL flag is used for waitpid() to assure not miss clone and normal process events.

2007-12-17libata: fix ATAPI drainingTejun Heo
With ATAPI transfer chunk size properly programmed, libata PIO HSM should be able to handle full spurious data chunks. Also, it's a good idea to suppress trailing data warning for misc ATAPI commands as there can be many of them per command - for example, if the chunk size is 16 and the drive tries to transfer 510 bytes, there can be 31 trailing data messages. This patch makes the following updates to libata ATAPI PIO HSM implementation. * Make it drain full spurious chunks. * Suppress trailing data warning message for misc commands. * Put limit on how many bytes can be drained. * If odd, round up consumed bytes and the number of bytes to be drained. This gets the number of bytes to drain right for drivers which do 16bit PIO. This patch is partial backport of improve-ATAPI-data-xfer patchset pending for #upstream.

2007-12-17libata-acpi: implement _GTF command filteringTejun Heo
Implement _GTF command filtering which can be controlled by libata.acpi_filter kernel parameter. Currently SETXFER and LOCK commands are filtered. libata configures transfer mode by itself and _GTF SETXFER commands can potentially disrupt device configuration. _GTM/_STM mechanism can't handle hotplugging too well and when _GTF is executed, controller is in PIO0 rather than the mode _STM configured. Note that detecting SET MAX LOCK requires looking at the previous command. This adds a bit to code complexity. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
