2008-11-01saner FASYNC handling on file closeAl Viro1-2/+0
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

2008-10-22IB/ehca: Reject dynamic memory add/remove when ehca adapter is presentStefan Roscher1-0/+48
Since the ehca device driver does not support dynamic memory add and remove operations, the driver must explicitly reject such requests in order to prevent unpredictable behaviors related to existing memory regions that cover all of memory being used by InfiniBand protocols in the kernel. The solution (for now at least) is to add a memory notifier to the ehca device driver and if a request for dynamic memory add or remove comes in, ehca will always reject it. The user can add or remove memory by hot-removing the ehca adapter, performing the memory operation, and then hot-adding the ehca adapter back.

2008-10-22IB/ehca: Fix reported max number of QPs and CQs in systems with >1 adapterStefan Roscher4-19/+26
Because ehca adapters can differ in the maximum number of QPs and CQs we have to save the maximum number of these ressources per adapter and not globally per ehca driver. This fix introduces 2 new members to the shca structure to store the maximum value for QPs and CQs per adapter. The module parameters are now used as initial values for those variables. If a user selects an invalid number of CQs or QPs we don't print an error any longer, instead we will inform the user with a warning and set the values to the respective maximum supported by the HW.

2008-10-22mlx4_core: Multiple port type supportYevgeny Petrilin3-5/+13
Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

2008-10-20x86: sysfs: kill owner field from attributeParag Warudkar1-1/+1
Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

Use krealloc() instead of kmalloc() followed by memcpy() when resizing the MAD module's snoop table.

2008-10-13vfs: Use const for kernel parser tableSteven Whitehouse1-1/+1
This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.

2008-10-13[SCSI] libiscsi: rename host reset to target resetMike Christie1-1/+1
I had this in my patchset to add target reset support, but it got dropped due to patching conflicts. This initial patch just renames the function and users. We are actually just dropping the session, and so this does not have anything to do with the host exactly. It does for software iscsi because we allocate a host per session, but for cxgb3i this makes no sense.

2008-10-13[SCSI] libiscsi: Support drivers initiating session removalMike Christie1-0/+1
If the driver knows when hardware is removed like with cxgb3i, bnx2i, qla4xxx and iser then we will want to remove the sessions/devices that are bound to that device before removing the host. cxgb3i and in the future bnx2i will remove the host and that will remove all the sessions on the hba. iser can call iscsi_kill_session when it gets an event that indicates that a hca is removed. And when qla4xxx is hooked in to the lib (it is only hooked into the class right now) it can call iscsi remove host like the partial offload card drivers.

2008-10-10IPoIB: Always initialize poll_timer to avoid crash on unloadRoland Dreier1-4/+3
ipoib_ib_dev_stop() does del_timer_sync(&priv->poll_timer), but if a P_key for an interface is not found, poll_timer is not initialized, so this leads to a crash or hang. Fix this by moving where poll_timer is initialized to ipoib_ib_dev_init(), which is always called. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1172>.

In case of error, the function ucma_alloc_multicast() returns a NULL pointer, but never returns an ERR pointer. So after a call to this function, an IS_ERR test should be replaced by a NULL test.
