2006-10-03[PATCH] IDE error handling fixesHua Zhong
In 2.6.15.1 I encountered some IDE crashes when unplugging IDE cables to emulate disk errors. Below is a patch against 2.6.16 which I think still applies. 1. The first BUG_ON could trigger when a PREFLUSH IO fails (it would fail the original barrier request which hasn't been marked REQ_STARTED yet). 2. the rq could have been dequeued already (same as 1). 3. HWGROUP(drive)->rq could be NULL because of the ide_error() several lines earlier.

2006-10-03[PATCH] sched: cleanup sched_group cpu_power setupSiddha, Suresh B
Up to now sched group's cpu_power for each sched domain is initialized independently. This made the setup code ugly as the new sched domains are getting added. Make the sched group cpu_power setup code generic, by using domain child field and new domain flag in sched_domain. For most of the sched domains(except NUMA), sched group's cpu_power is now computed generically using the domain properties of itself and of the child domain. sched groups in NUMA domains are setup little differently and hence they don't use this generic mechanism.

2006-10-03[PATCH] sched: force /sbin/init off isolated cpusNick Piggin
Force /sbin/init off isolated cpus (unless every CPU is specified as an isolcpu). Users seem to think that the isolated CPUs shouldn't have much running on them to begin with. That's fair enough: intuitive, I guess. It also means that the cpu affinity masks of tasks will not include isolcpus by default, which is also more intuitive, perhaps. /sbin/init is spawned from the boot CPU's idle thread, and /sbin/init starts the rest of userspace. So if the boot CPU is specified to be an isolcpu, then prior to this patch, all of userspace will be run there. (throw in a couple of plausible devinit -> cpuinit conversions I spotted while we're here).

2006-10-03[PATCH] restore parport_pc probing on powermacOlaf Hering
The last change for partport_pc did fix the common case for all PowerMacs, but it broke the case for PCI multiport IO cards. In fact, the config option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed the parport driver. It enables the winbond and smsc probing. Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will take care of it. All powerpc configs should have CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp boards we tested it on.

2006-10-03[PATCH] Create kallsyms_lookup_size_offset()Franck Bui-Huu
Some uses of kallsyms_lookup() do not need to find out the name of a symbol and its module's name it belongs. This is specially true in arch specific code, which needs to unwind the stack to show the back trace during oops (mips is an example). In this specific case, we just need to retreive the function's size and the offset of the active intruction inside it. Adds a new entry "kallsyms_lookup_size_offset()" This new entry does exactly the same as kallsyms_lookup() but does not require any buffers to store any names. It returns 0 if it fails otherwise 1.

2006-10-03[PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbersDavid Howells
These patches make the kernel pass 64-bit inode numbers internally when communicating to userspace, even on a 32-bit system. They are required because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS for example. The 64-bit inode numbers are then propagated to userspace automatically where the arch supports it. Problems have been seen with userspace (eg: ld.so) using the 64-bit inode number returned by stat64() or getdents64() to differentiate files, and failing because the 64-bit inode number space was compressed to 32-bits, and so overlaps occur. This patch: Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit inode number so that 64-bit inode numbers can be passed back to userspace. The stat functions then returns the full 64-bit inode number where available and where possible. If it is not possible to represent the inode number supplied by the filesystem in the field provided by userspace, then error EOVERFLOW will be issued. Similarly, the getdents/readdir functions now pass the full 64-bit inode number to userspace where possible, returning EOVERFLOW instead when a directory entry is encountered that can't be properly represented. Note that this means that some inodes will not be stat'able on a 32-bit system with old libraries where they were before - but it does mean that there will be no ambiguity over what a 32-bit inode number refers to. Note similarly that directory scans may be cut short with an error on a 32-bit system with old libraries where the scan would work before for the same reasons. It is judged unlikely that this situation will occur because modern glibc uses 64-bit capable versions of stat and getdents class functions exclusively, and that older systems are unlikely to encounter unrepresentable inode numbers anyway.

The race is as follows: A process : cma_process_remove() calls cma_remove_id_dev(), which sets id state to CMA_DEVICE_REMOVAL and calls wait_event(dev_remove). B process : cma_req_handler() had incremented dev_remove, and calls cma_acquire_ib_dev() and on failure calls cma_release_remove(), which does a wake_up of cma_process_remove(). Then cma_req_handler() calls rdma_destroy_id(); A Process : cma_remove_id_dev() gets woken and checks the state of id, and since it is still (wrongly) CMA_DEVICE_REMOVAL, it calls notify_user(id) and if that fails, the caller - cma_process_remove() calls rdma_destroy_id(id). Two processes can call rdma_destroy_id(), resulting in one de-referencing kfreed id_priv. Fix is for process B to set CMA_DESTROYING in cma_req_handler() so that process A will return instead of doing a rdma_destroy_id().
