* Tweak /proc/ipmi removalAlexey Dobriyan2007-10-17
| | | | | | | | | | | | | | | | Driver does proc_mkdir("ipmi", NULL); but remove_proc_entry(proc_ipmi_root->name, &proc_root); This is OK and working if only slightly inconsistent. Also changing proc_root to NULL will help OpenVZ which has multiple proc roots and, as we now know, requires matching parents in such cases.

* handle the multi-threaded init's exit() properlyOleg Nesterov2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With or without this patch, multi-threaded init's are not fully supported, but do_exit() is completely wrong. This becomes a real problem when we support pid namespaces. 1. do_exit() panics when the main thread of /sbin/init exits. It should not until the whole thread group exits. Move the code below, under the "if (group_dead)" check. Note: this means that forget_original_parent() can use an already dead child_reaper()'s task_struct. This is OK for /sbin/init because - do_wait() from alive sub-thread still can reap a zombie, we iterate over all sub-thread's ->children lists - do_notify_parent() will wakeup some alive sub-thread because it sends the group-wide signal However, we should remove choose_new_parent()->BUG_ON(reaper->exit_state) for this. 2. We are playing games with ->nsproxy->pid_ns. This code is bogus today, and it has to be changed anyway when we really support pid namespaces, just remove it.

* Deprecate a.out ELF interpretersAndi Kleen2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | The Linux ELF loader is quite complicated and messy code (that could probably need a rewrite, but that's a different chapter). One particular messy part in it is the support for non ELF a.out ld.sos. This was originally added to make transition from a.out to ELF easier because an a.out ELF ld.so could be still build using an older a.out toolkit. But by now that should be fully obsolete and removing it would clean up binfmt_elf.c up a bit. I propose to deprecate this support and remove for 2.6.25. Drawback is that someone still runs their system with a.out ld.so they would need to update the ld.so when updating to a new kernel. This patch just adds an entry to the deprecation file and a printk warning users.

* core_pattern: ignore RLIMIT_CORE if core_pattern is a pipeNeil Horman2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time /proc/sys/kernel/core_pattern has been able to set its output destination as a pipe, allowing a user space helper to receive and intellegently process a core. This infrastructure however has some shortcommings which can be enhanced. Specifically: 1) The coredump code in the kernel should ignore RLIMIT_CORE limitation when core_pattern is a pipe, since file system resources are not being consumed in this case, unless the user application wishes to save the core, at which point the app is restricted by usual file system limits and restrictions. 2) The core_pattern code should be able to parse and pass options to the user space helper as an argv array. The real core limit of the uid of the crashing proces should also be passable to the user space helper (since it is overridden to zero when called). 3) Some miscellaneous bugs need to be cleaned up (specifically the recognition of a recursive core dump, should the user mode helper itself crash. Also, the core dump code in the kernel should not wait for the user mode helper to exit, since the same context is responsible for writing to the pipe, and a read of the pipe by the user mode helper will result in a deadlock. This patch: Remove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that core_pattern is a pipe, the entire core will be fed to the user mode helper.

| | | | | | | | | | | | | | | | | | | | | | | | | Add in support for SunOS 4.1.x flavor of BSD 4.2 UFS filing system Macros have been put in to alow suport for the old static table Cylinder Groups but this implementation does not use them yet. This also fixes Solaris UFS filing system access by disabling fast symbolic links as Sun's version of UFS does not support on-disk fast symbolic links. Tested by: Ppartitioning a new disk using SunOS 4.1.1, creating a UFS filing system on one of the partitions and writing some files to the filing system. Using Linux-2.6.22 (patched) to read the files and then write a shed load of files to the UFS partition. Using SunOS 4.1.1 to verify the filing system is OK and to check the files. The test host is a sun4c SS1 Clone.

* ext2: show all mount optionsMiklos Szeredi2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | Using mtab is problematic for various reasons, one of them is that unprivileged mounts won't turn up in there. So we want to get rid of it, and use /proc/mounts instead. But most filesystems are lazy, and are not showing all mount options. Which means, that without mtab, the user won't be able to see some or all of the options. It would be nice if the generic code could remember the mount options, and show them without the need to add extra code to filesystems. But this is not easy, because different filesystems handle mount options given options, and not tough the rest. This is not taken into account by mount(8) either, so /etc/mtab will be broken in this case. This series fixes up ->show_options() in ext[234].

* Remove sysctl.h from fs.hAlexey Dobriyan2007-10-17
| | | | | | | | | | Rrrr, addition of sysctl.h to fs.h was't very smart, because simple editing of the former will buy you big recompile, where it shouldn't have to.

* pcmcia: CompactFlash driver for PA Semi Electra boardsOlof Johansson2007-10-17
| | | | | | | | | | | | | | | | | | | | | | Driver for the CompactFlash slot on the PA Semi Electra eval board. It's a simple device sitting on localbus, with interrupts and detect/voltage control over GPIO. The driver is implemented as an of_platform driver, and adds localbus as a bus being probed by the of_platform framework.

* fs/proc/mmu.c: headers butcheryAlexey Dobriyan2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | fs/proc/mmu.c consists of only one function which uses only: 1) struct vmalloc_info * 2) struct vm_struct * 3) struct vmalloc_info 4) vmlist 5) VMALLOC_TOTAL, VMALLOC_START, VMALLOC_END 6) read_lock, read_unlock 7) vmlist_lock 8) struct vm_struct This gives us linux/spinlock.h, asm/pgtable.h, "internal.h", linux/vmalloc.h. asm/pgtable.h uses PKMAP_BASE on i386, for which asm/highmem.h is needed. But, linux/highmem.h is actually used to make it compile everywhere. I'll deal later with this particular i386 surprise. Cross-compile tested on many archs and configs.

* do_poll: return -EINTR when signalledOleg Nesterov2007-10-17
| | | | | | | | | | | | | | do_poll() checks signal_pending() but returns 0 when interrupted. This means the caller has to check signal_pending() again. Change it to return -EINTR when signal_pending() and count == 0.

* do_sys_poll: simplify playing with on-stack dataOleg Nesterov2007-10-17
| | | | | | | | | | | | | | | | | | | Cleanup. Lessens both the source and compiled code (100 bytes) and imho makes the code much more understandable. With this patch "struct poll_list *head" always points to on-stack stack_pps, so we can remove all "is it on-stack" and "was it initialized" checks. Also, move poll_initwait/poll_freewait and -EINTR detection closer to the do_poll()'s callsite.

* fs/romfs/inode.c: trivial improvementsWANG Cong2007-10-17
| | | | | | | | | | | | - There are no lists in fs/romfs/inode.c, so using list_entry is a bit confusing. Replace it with container_of. - It is unnecessary to cast the return value of kmem_cache_alloc, since it returns a void* pointer.

* nbd: change a parameter's type to remove a memcpy callDenis Cheng2007-10-17
| | | | | | | | | | | | | | This memcpy looks so strange, in fact it's merely a pointer dereference, so I change the parameter's type to refer it more directly, this could make the memcpy not needed anymore. In the function nbd_read_stat where nbd_find_request is only once called, the parameter served should be transformed accordingly.
