2006-04-26[PATCH] Add support for the sys_vmsplice syscallJens Axboe
sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice() moves data to a pipe, with the input being a user address range instead. This uses an approach suggested by Linus, where we can hold partial ranges inside the pages[] map. Hopefully this will be useful for network receive support as well.

2006-04-26[PATCH] splice: fix offset problemsJens Axboe
Make the move_from_pipe() actors return number of bytes processed, then move_from_pipe() can decide more cleverly when to move on to the next buffer. This fixes problems with pipe offset and differing file offset. Signed-off-by: Jens Axboe <axboe@suse.de>

2006-04-24[NETFILTER]: nf_conntrack: Fix module refcount dropping too farYasuyuki Kozakai
If nf_ct_l3proto_find_get() fails to get the refcount of nf_ct_l3proto_generic, nf_ct_l3proto_put() will drop the refcount too far. This gets rid of '.me = THIS_MODULE' of nf_ct_l3proto_generic so that nf_ct_l3proto_find_get() doesn't try to get refcount of it. It's OK because its symbol is usable until nf_conntrack.ko is unloaded. This also kills unnecessary NULL pointer check as well. __nf_ct_proto_find() allways returns non-NULL pointer.

2006-04-22[PATCH] tpm: new 1.2 sysfs filesKylene Jo Hall
Many of the sysfs files were calling the TPM_GetCapability command with array. Since for 1.2 more sysfs files of this type are coming I am generalizing the array so there can be one array and the unique parts can be filled in just before the command is called.

2006-04-22[PATCH] tpm: command duration updateKylene Jo Hall
With the TPM 1.2 Specification, each command is classified as short, medium or long and the chip tells you the maximum amount of time for a response to each class of command. This patch provides and array of the classifications and a function to determine how long the response should be waited for. Also, it uses that information in the command processing to determine how long to poll for. The function is exported so the 1.2 driver can use the functionality to determine how long to wait for a DataAvailable interrupt if interrupts are being used.

2006-04-22[PATCH] tpm: spacing cleanupsKylene Jo Hall
The following patch set contains numerous changes to the base tpm driver (tpm.c) to support the next generation of TPM chips. The changes include new sysfs files because of more relevant data being available, a function to access the timeout and duration values for the chip, and changes to make use of those duration values. Duration in the TPM specification is defined as the maximum amount of time the chip could take to return the results. Commands are in one of three categories short, medium and long. Also included are cleanups of how the commands for the sysfs files are composed to reduce a bunch of redundant arrays. This patch: Fix minor spacing issues.

This still races with other simultaneous alloc_iommu or free_iommu(size > 1) which both use bus-unlocked operations.

2006-04-22[PATCH] add migratepage address space op to shmemLee Schermerhorn
Basic problem: pages of a shared memory segment can only be migrated once. In 2.6.16 through 2.6.17-rc1, shared memory mappings do not have a migratepage address space op. Therefore, migrate_pages() falls back to default processing. In this path, it will try to pageout() dirty pages. Once a shared memory page has been migrated it becomes dirty, so migrate_pages() will try to page it out. However, because the page count is 3 [cache + current + pte], pageout() will return PAGE_KEEP because is_page_cache_freeable() returns false. This will abort all subsequent migrations. This patch adds a migratepage address space op to shared memory segments to avoid taking the default path. We use the "migrate_page()" function because it knows how to migrate dirty pages. This allows shared memory segment pages to migrate, subject to other conditions such as # pte's referencing the page [page_mapcount(page)], when requested. I think this is safe. If we're migrating a shared memory page, then we found the page via a page table, so it must be in memory.
