* [PATCH] Add tmpfs options for memory placement policiesRobin Holt2006-01-146-15/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Anything that writes into a tmpfs filesystem is liable to disproportionately decrease the available memory on a particular node. Since there's no telling what sort of application (e.g. dd/cp/cat) might be dropping large files there, this lets the admin choose the appropriate default behavior for their site's situation. Introduce a tmpfs mount option which allows specifying a memory policy and a second option to specify the nodelist for that policy. With the default policy, tmpfs will behave as it does today. This patch adds support for preferred, bind, and interleave policies. The default policy will cause pages to be added to tmpfs files on the node which is doing the writing. Some jobs expect a single process to create and manage the tmpfs files. This results in a node which has a significantly reduced number of free pages. With this patch, the administrator can specify the policy and nodes for that policy where they would prefer allocations. This patch was originally written by Brent Casavant and Hugh Dickins. I added support for the bind and preferred policies and the mpol_nodelist mount option.

* [PATCH] Watchdog: Winsystems EPX-C3 SBCCalin A. Culianu2006-01-143-0/+239
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a 2.6 patch that adds support for the watchdog timer built into the EPX-C3 single board computer manufactured by Winsystems, Inc. Driver details: This is for x86 only. This watchdog is pretty basic and simple. It is only configurable via jumpers on the SBC, and it only has either a 1.5s or 200s interval. The watchdog can either be auto-configured to start as soon as the machine powers up (bad idea for the 1.5s interval!) or it can be enabled and disabled by writing to io port 0x1ee. Petting the watchdog involves writing any value to io port 0x1ef. The only unfortunate thing about this watchdog (and it is not at all uncommmon in watchdogs that linux supports) is that it is not a PCI or ISA-PNP device and as such it isn't at all probeable. Either the watchdog exists as 2 bytes at 0x1ee, or it doesn't. Thus, using this driver on a machine that doesn't have that watchdog can potentially hang/crash the system, etc. So only use this driver if you in fact are on a Winsystems EPX-C3 SBC. Anyway this driver fits into the already-existing watchdog framework quite nicely and I already tested it on my EPX-C3 and it works like a charm. Signed-off-by: Calin A.

* [PATCH] sched: add new SCHED_BATCH policyIngo Molnar2006-01-143-19/+40
| | | | | | | | | | | | | | Add a new SCHED_BATCH (3) scheduling policy: such tasks are presumed CPU-intensive, and will acquire a constant +5 priority level penalty. Such policy is nice for workloads that are non-interactive, but which do not want to give up their nice levels. The policy is also useful for workloads that want a deterministic scheduling policy without interactivity causing extra preemptions (between that workload's tasks).

| | | | | | | | | | | | | | | Add driver support for a 2 port PCI IOC3-based serial card on Altix boxes: This is a re-submission. On the original submission I was asked to organize the code so that the MIPS ioc3 ethernet and serial parts could be used with this driver. Stanislaw Skowronek was kind enough to provide the shim layer for this - thanks Stanislaw. This patch includes the shim layer and the Altix PCI ioc3 serial driver.

* [PATCH] Fix double decrement of mqueue_mnt->mnt_count in sys_mq_openAlexander Viro2006-01-141-26/+33
| | | | | | | | | | | | | | | | | | Fixed the refcounting on failure exits in sys_mq_open() and cleaned the logics up. Rules are actually pretty simple - dentry_open() expects vfsmount and dentry to be pinned down and it either transfers them into created struct file or drops them. Old code had been very confused in that area - if dentry_open() had failed either in do_open() or do_create(), we ended up dentry and mqueue_mnt dropped twice, once by dentry_open() cleanup and then by sys_mq_open(). Fix consists of making the rules for do_create() and do_open() same as for dentry_open() and updating the sys_mq_open() accordingly; that actually leads to more straightforward code and less work on normal path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem report (against 2.4.x driver) from Jeff Layton <jlayton@redhat.com>: An OEM noticed that the U6 qla2200 driver would hang for around 2 minutes at boot time and then proceed normally. I found that the delay was occurring when loading the new firmware into the card, and was due to a schedule_timeout(10) added to the bottom of the polling loop. Some testing showed that the load ram operation on the card was very quick (on the order of a couple of jiffies), but the sleep in the polling loop was making each operation take around 25-30. The attached patch corrects this by making it skip sleeping during the load ram operation, since I believe we only do that when the module is plugged in. It also skips sleeping if the mbox_int flag got set during the current loop. This corrected the hang on my test setup, and OEM also confirmed that it corrected the problem for them.

We had thought page_count could be used to work around this, but the correct test is for PageSlab. The proper solution is to figure out what type of pages filesystems can use so we do not have to add tests like this or handle it in the block layer for all network block drivers but the issue still has not been resolved on fs-devel so we are sending this patch as a temporary fix. This is last patch just in case it is Nakd with the explanation that we need to push the correct fix through fs-devel, mm or the block layer. The rest of the patchset can live without the patch, but the driver will not work with filesystems like XFS.

Instead of doing the lib, I just kept everything in scsi_trnapsort_iscsi.c like the FC and SPI class. This was becuase the driver model and sysfs class is tied to the session and connection setup so separating did not buy very much at this time. The reason for this patch was becuase HW iscsi LLDs like qla4xxx cannot use the iscsi class becuase the scsi_host was tied to the interface and class code. This patch just seperates the session from scsi host so that LLDs that allocate the host per some resource like pci device can still use the class. This is also fixes a couple refcount bugs that can be triggered when users have a sysfs file open, close the session, then read or write to the file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When James Smart fixed the issue of the userspace scan atributes crashing the system with the FC transport class he added a patch to let the transport class check if the parent is valid for a given transport class. When adding support for the integrated raid of fusion sas devices we ran into a problem with that, as it didn't allow adding virtual raid volumes without the transport class knowing about it. So this patch adds a user_scan attribute instead, that takes over from scsi_scan_host_selected if the transport class sets it and thus lets the transport class control the user-initiated scanning. As this plugs the hole about user-initiated scanning the target_parent hook goes away and we rely on callers of the scanning routines to do something sensible. For SAS this meant I had to switch from a spinlock to a mutex to synchronize the topology linked lists, in FC they were completely unsynchronized which seems wrong.

| * [SCSI] mptsas: support basic hotplugChristoph Hellwig2006-01-142-31/+308
| | | | | | | | | | | | | | | | | | | | Adds hotplug support for SAS end devices. Unfortunately the fusion firmware doesn't generate similar events for expanders addition/removal so we can't support them yet. Eric has an idea about a clever scheme to find out about expander changes so that'll be added later on.

| * [SCSI] I2O: move pci_request_regions() just behind pci_enable_device()Salyzyn, Mark2006-01-142-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem in dpt_i2o could be the pci config space accesses it triggers as it loads, dangerous to do if there is any I/O activity going on in the other driver (probable if a boot driver I guess). I approve this patch to dpt_i2o.c, and am applying it to the Adaptec branch of the driver. Thanks for the investigation Ryoji. --- In linux 2.6.15, data transfer does hang when both dpt_i2o and i2o_block drivers are loaded. It seems that location of pci_request_regions() are wrong. I moved it just behind pci_enable_device() like other drivers, and it becomes fine. Signed-off-by: Ryoji Kamei <kamei@miraclelinux.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
