2008-07-13cpusets, hotplug, scheduler: fix scheduler domain breakageDmitry Adamushko
Commit f18f982ab ("sched: CPU hotplug events must not destroy scheduler domains created by the cpusets") introduced a hotplug-related problem as described below: Upon CPU_DOWN_PREPARE, update_sched_domains() -> detach_destroy_domains(&cpu_online_map) does the following: /* * Force a reinitialization of the sched domains hierarchy. The domains * and groups cannot be updated in place without racing with the balancing * code, so we temporarily attach all running cpus to the NULL domain * which will prevent rebalancing while the sched domains are recalculated. */ The sched-domains should be rebuilt when a CPU_DOWN ops. has been completed, effectively either upon CPU_DEAD{_FROZEN} (upon success) or CPU_DOWN_FAILED{_FROZEN} (upon failure -- restore the things to their initial state). That's what update_sched_domains() also does but only for !CPUSETS case. With f18f982ab, sched-domains' reinitialization is delegated to CPUSETS code: cpuset_handle_cpuhp() -> common_cpu_mem_hotplug_unplug() -> rebuild_sched_domains() Being called for CPU_UP_PREPARE and if its callback is called after update_sched_domains()), it just negates all the work done by update_sched_domains() -- i.e. a soon-to-be-offline cpu is included in the sched-domains and that makes it visible for the load-balancer while the CPU_DOWN ops. is in progress. __migrate_live_tasks() moves the tasks off a 'dead' cpu (it's already "offline" when this function is called). try_to_wake_up() is called for one of these tasks from another CPU -> the load-balancer (wake_idle()) picks up a "dead" CPU and places the task on it. Then e.g. BUG_ON(rq->nr_running) detects this a bit later -> oops.

2008-07-12cifs: fix wksidarr declaration to be big-endian friendlyJeff Layton
The current definition of wksidarr works fine on little endian arches (since cpu_to_le32 is a no-op there), but on big-endian arches, it fails to compile with this error: error: braced-group within expression allowed only inside a function The problem is that this static declaration has cpu_to_le32 embedded within it, and that expands into a function macro. We need to use __constant_cpu_to_le32() instead.

2008-07-12cifs: fix inode leak in cifs_get_inode_info_unixJeff Layton
Try this: mount a share with unix extensions create a file on it umount the share You'll get the following message in the ring buffer: VFS: Busy inodes after unmount of cifs. Self-destruct in 5 seconds. Have a nice day... ...the problem is that cifs_get_inode_info_unix is creating and hashing a new inode even when it's going to return error anyway. The first lookup when creating a file returns an error so we end up leaking this inode before we do the actual create. This appears to be a regression caused by commit 0e4bbde94fdc33f5b3d793166b21bf768ca3e098. The following patch seems to fix it for me, and fixes a minor formatting nit as well.

2008-07-12ov7670: clean up ov7670_read semanticsAndres Salomon
Cortland Setlow pointed out a bug in ov7670.c where the result from ov7670_read() was just being checked for !0, rather than <0. This made me realize that ov7670_read's semantics were rather confusing; it both fills in 'value' with the result, and returns it. This is goes against general kernel convention; so rather than fixing callers, let's fix the function. This makes ov7670_read return <0 in the case of an error, and 0 upon success. Thus, code like: res = ov7670_read(...); if (!res) goto error; ..will work properly.

2008-07-12fbdev: bugfix for multiprocess defioJaya Kumar
This patch is a bugfix for how defio handles multiple processes manipulating the same framebuffer. Thanks to Bernard Blackham for identifying this bug. It occurs when two applications mmap the same framebuffer and concurrently write to the same page. Normally, this doesn't occur since only a single process mmaps the framebuffer. The symptom of the bug is that the mapping applications will hang. The cause is that defio incorrectly tries to add the same page twice to the pagelist. The solution I have is to walk the pagelist and check for a duplicate before adding. Since I needed to walk the pagelist, I now also keep the pagelist in sorted order.

2008-07-12[SCSI] bsg: fix oops on removeJames Bottomley
If you do a modremove of any sas driver, you run into an oops on shutdown when the host is removed (coming from the host bsg device). The root cause seems to be that there's a use after free of the bsg_class_device: In bsg_kref_release_function, this is used (to do a put_device(bcg->parent) after bcg->release has been called. In sas (and possibly many other things) bcd->release frees the queue which contains the bsg_class_device, so we get a put_device on unreferenced memory. Fix this by taking a copy of the pointer to the parent before releasing bsg.

2008-07-12[SCSI] fusion: default MSI to disabled for SPI and FC controllersJames Bottomley
There's a fault on the FC controllers that makes them not respond correctly to MSI. The SPI controllers are fine, but are likely to be onboard on older motherboards which don't handle MSI correctly, so default both these cases to disabled. Enable by setting the module parameter mpt_msi_enable=1. For the SAS case, enable MSI by default, but it can be disabled by setting the module parameter mpt_msi_enable=0.

2008-07-11Fix reference counting race on log buffersDave Chinner
When we release the iclog, we do an atomic_dec_and_lock to determine if we are the last reference and need to trigger update of log headers and writeout. However, in xlog_state_get_iclog_space() we also need to check if we have the last reference count there. If we do, we release the log buffer, otherwise we decrement the reference count. But the compare and decrement in xlog_state_get_iclog_space() is not atomic, so both places can see a reference count of 2 and neither will release the iclog. That leads to a filesystem hang. Close the race by replacing the atomic_read() and atomic_dec() pair with atomic_add_unless() to ensure that they are executed atomically.

2008-07-11libata-acpi: filter out DIPM enableTejun Heo
Some BIOSen enable DIPM via _GTF which causes command timeouts under certain configuration. This didn't occur on 2.6.25 because 2.6.25 defaulted to SRST, so _GTF wasn't executed during boot probe, so ahci host reset disabled DIPM and as _GTF wasn't executed after SRST, DIPM wasn't enabled. On 2.6.26, hardreset is used during probe and after probe _GTF is executed enabling DIPM and thus the failures. This patch could theoretically disable DIPM on machines which used to have it enabled on 2.6.25 but AFAIK ahci is currently the only driver which uses SATA ACPI hierarchy (_SDD) and as the host reset would have always disabled DIPM, this shouldn't happen.
