2009-01-05af_iucv: Free iucv path/socket in path_pending callbackHendrik Brueckner
Free iucv path after iucv_path_sever() calls in iucv_callback_connreq() (path_pending() iucv callback). If iucv_path_accept() fails, free path and free/kill newly created socket.

2009-01-05af_iucv: New error return codes for connect()Hendrik Brueckner
If the iucv_path_connect() call fails then return an error code that corresponds to the iucv_path_connect() failure condition; instead of returning -ECONNREFUSED for any failure. This helps to improve error handling for user space applications (e.g. inform the user that the z/VM guest is not authorized to connect to other guest virtual machines). The error return codes are based on those described in connect(2).

2009-01-05get rid of the last symlink in uml buildAl Viro
We need to make asm-offsets.h contents visible for objects built with userland headers. Instead of creating a symlink, just have the file with equivalent include (relative to location of header) created once. That kills the last symlink used in arch/um builds. Additionally, both generated headers can become dependencies of archprepare now, killing the misuse of prepare.

2009-01-05dmaengine: remove dependency on async_txDan Williams
async_tx.ko is a consumer of dma channels. A circular dependency arises if modules in drivers/dma rely on common code in async_tx.ko. It prevents either module from being unloaded. Move dma_wait_for_async_tx and async_tx_run_dependencies to dmaeninge.o where they should have been from the beginning.

2009-01-05async_tx, dmaengine: document channel allocation and api reworkDan Williams
"Wouldn't it be better if the dmaengine layer made sure it didn't pass the same channel several times to a client? I mean, you seem concerned that the memcpy() API should be transparent and easy to use, but the whole registration interface is just ridiculously complicated..." - Haavard The dmaengine and async_tx registration/allocation interface is indeed needlessly complicated. This redesign has the following goals: 1/ Simplify reference counting: dma channels are not something one would expect to be hotplugged, it should be an exceptional event handled by drivers not something clients should be mandated to handle in a callback. The common case channel removal event is 'rmmod <dma driver>', which for simplicity should be disallowed if the channel is in use. 2/ Add an interface for requesting exclusive access to a channel suitable to device-to-memory users. 3/ Convert all memory-to-memory users over to a common allocator, the goal here is to not have competing channel allocation schemes. The only competition should be between device-to-memory exclusive allocations and the memory-to-memory usage case where channels are shared between multiple "clients".

2009-01-05net/ehea: bitops work on unsigned longsStephen Rothwell
The flags field of struct ehea_port is only used with test_bit(), clear_bit() and set_bit() and these interfaces only work on "unsigned long"s, so change the field to be an "unsigned long". Also, this field only has two bits defined for it (0 and 1) so will still be fine if someone builds this driver for a 32 bit arch (at least as far as this flags field is concerned). Also note that ehea_driver_flags is only used in ehca_main.c, so make it static in there. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

This reverts commit 22604c866889c4b2e12b73cbf1683bda1b72a313. We can't fix this issue in this way, because we now can try to take the dev_base_lock rwlock as a writer in software interrupt context and that is not allowed without major surgery elsewhere.

2009-01-05Btrfs: Fix free block discard calls down to the block layerLiu Hui
This is a patch to fix discard semantic to make Btrfs work with FTL and SSD. We can improve FTL's performance by telling it which sectors are freed by file system. But if we don't tell FTL the information of free sectors in proper time, the transaction mechanism of Btrfs will be destroyed and Btrfs could not roll back the previous transaction under the power loss condition. There are some problems in the old implementation: 1, In __free_extent(), the pinned down extents should not be discarded. 2, In free_extents(), the free extents are all pinned, so they need to be discarded in transaction committing time instead of free_extents(). 3, The reserved extent used by log tree should be discard too. This patch change discard behavior as follows: 1, For the extents which need to be free at once, we discard them in update_block_group(). 2, Delay discarding the pinned extent in btrfs_finish_extent_commit() when committing transaction. 3, Remove discarding from free_extents() and __free_extent() 4, Add discard interface into btrfs_free_reserved_extent() 5, Discard sectors before updating the free space cache, otherwise, FTL will destroy file system data.

It really should never happen in the kernel, since the kernel can guarantee it won't get the access rights failure (highest privilege level, and can set %sr and %protid to whatever it wants.) It really genuinely is a bug that probably should panic the kernel. The only precedent I can easily see is x86 fixing up a bad iret with a general protection fault, which is more or less analogous to code 27 here. On the other hand, taking the exception on a userspace access really isn't all that critical, and there's fundamentally little reason for the kernel not to SIGSEGV the process, and continue... Argh. (btw, I've instrumented my do_sys_poll with a pile of assertions that %cr8 << 1 == %sr3 == current->mm.context... let's see if where we're getting corrupted is deterministic, though, I would guess that it won't be.)

parisc: add uevent helper for parisc bus udev device-driver auto detection was failing to work on the GSC bus, since udev didn't knew wich driver to load due to a missing MODALIAS environment variable from kernel. This patch fixes this by adding the MODALIAS environment variable to the uevent kernel notifications. Since modalias_show() generated the modalias string already, I splitted this out and created a new static function make_modalias() which is now used by modalias_show() and the new parisc_uevent() function.

2009-01-05inotify: fix type errors in interfacesMichael Kerrisk
The problems lie in the types used for some inotify interfaces, both at the kernel level and at the glibc level. This mail addresses the kernel problem. I will follow up with some suggestions for glibc changes. For the sys_inotify_rm_watch() interface, the type of the 'wd' argument is currently 'u32', it should be '__s32' . That is Robert's suggestion, and is consistent with the other declarations of watch descriptors in the kernel source, in particular, the inotify_event structure in include/linux/inotify.h: struct inotify_event { __s32 wd; /* watch descriptor */ __u32 mask; /* watch mask */ __u32 cookie; /* cookie to synchronize two events */ __u32 len; /* length (including nulls) of name */ char name[0]; /* stub for possible name */ }; The patch makes the changes needed for inotify_rm_watch().
