      [PATCH] class_simple cleanup in sg · 20e358f2
      Chris Wright authored
      The only spot that seems to care about class_simple_device_add possibly
      failing, but it gets the wrong error test.

      What happens if that class_simple_create() fails?  Actually,
      class_simple_device_add could fail too, but doesn't seem anybody is
      checking for that.

      need to destroy the class on error path to avoid leak.

      ditto.  this will leak and would cause oops on reload of module.

      [PATCH] minor slab cleanups for hotplug CPUs · bd7c5d21
      Rusty Russell authored
      - Move free_block prototype, and ac_entry and ac_data functions up in file.
      
      - Use list_for_each_entry in cpuup_callback.
      
      - Remove unneccessary g_cpucache_up in cpuup_callback.
      
      - Make reap_timer_func take CPU number as data, and check if that is
        offline before rescheduing (noop without CONFIG_HOTPLUG_CPU).

      [PATCH] remove sparc64's num_possible_cpus() · 9f989ac8
      Rusty Russell authored
      Levent Serinol <levent.serinol@mynet.com> found that the hotplug cpu
      patch broke Sparc64.  I introduced a num_possible_cpus(), which
      Sparc64 already has.  Remove the Sparc64 one.
      
      I also removed Sparc64's cpu_online() macro: it's in linux/cpumask.h
      already.

      [PATCH] minor cleanups for hotplug CPUs · a59d2e4e
      Rusty Russell authored
      Note that without CONFIG_HOTPLUG_CPU, online cpus == possible cpus, so
      substitutions are a noop.
      
      - Changes show_stat to print out stats for every possible cpu, not
        just online CPUs.
      
      - Allocate mem in stat_open on possible, not online_cpus.
      
      - Add conventient macros to cpu.h: especially cpu_is_offline() for
        testing if a cpu is still online.
      
      - Add a num_possible_cpus() similar to num_online_cpus(), and define
        cpu_possible_mask for UP.
      
      - Allow printk on down cpus once system is running.
      
      - Mask cpumask with possible, not online cpus, for sys_getaffinity().

      [PATCH] introduce __drain_pages() to take a CPU number · 33a7ddaa
      Rusty Russell authored
      Extracts core of drain_pages() for hotcpu use.  Trivial.
      
      Hotplug CPU needs to drain pages on a downed CPU (usually it's the
      current cpu).  Introduce "__drain_pages", make the CPU an argument,
      and expose it if CONFIG_HOTPLUG_CPU as well as CONFIG_PM.

      [libata sata_promise] provide proper SCSI completion function · 4cb629dd
      Jeff Garzik authored
      Promise driver uses a custom error handling function, so we need
      the fix that was applied to the libata core:  the SCSI error

      Ok, found it.
      
      It really looks like the new EISA probing code in hp100 never got
      tested, since a precious offset has disappeared during the rewriting
      process.
      
      Please note that you still need to enable the device by hand, since
      your BIOS (or maybe the EISA CFG file, since I'm seeing the exact same
      problem on a Compaq machine here) doesn't properly enable the card.
      
      Here is what I'm getting on my test system :
      
      EISA: Probing bus 0 at 0000:00:0f.0
      EISA: Mainboard CPQ0541 detected.

      [PATCH] stop_machine_run: Move Bogolock Code Out of module.c · 80037662
      Rusty Russell authored
      The "bogolock" code was introduced in module.c, as a way of freezing
      the machine when we wanted to remove a module.  This patch moves it
      out to stop_machine.c and stop_machine.h.
      
      Since the code changes affinity and proirity, it's impolite to hijack
      the current context, so we use a kthread.  This means we have to pass
      the function rather than implement "stop_machine()" and
      "restart_machine()".

      JFS: Avoid incrementing i_count on file create · 64194c24
      Dave Kleikamp authored
      Committing a transaction creating a file required insuring that the
      inode stayed in cache until the journal was written to.  i_count was
      being incremented until the transaction was complete.
      
      However, incrementing i_count caused fcntl(S_SETLEASE) to fail.  I
      reworked the transaction code so that the inode does not have to
      stay in-memory while the transaction is being committed.
      
      Thanks to Steve French for figuring out why setlease was failing.

      JFS: warn users of inaccessible file names · e2423dc0
      Dave Kleikamp authored
      When no iocharset is specified, the default action is to trivially
      map each byte into the low order of the 16-bit unicode character.
      If an existing name exists that has a non-zero high order byte, the
      file will be inaccessible without remounting with iocharset set to
      a charset that supports the character.
      
      This patch will cause a warning to be issued to the syslog (no more
      than five times) suggesting that the volume be mounted with
      iocharset=utf8 in order to access the file.

      [PATCH] vma corruption fix · bc3d0059
      Andrew Morton authored
      From: Hugh Dickins <hugh@veritas.com>
      
      Fixes bugzilla #2219
      
      fork's dup_mmap leaves child mm_rb as copied from parent mm while doing all
      the copy_page_ranges, and then calls build_mmap_rb without holding
      page_table_lock.
      
      try_to_unmap_one's find_vma (holding page_table_lock not mmap_sem) coming
      on another cpu may cause mm mayhem.  It may leave the child's mmap_cache
      pointing to a vma of the parent mm.
      
      When the parent exits and the child faults, quite what happens rather
      depends on what junk then inhabits vm_page_prot, which gets set in the page
      table, with page_add_rmap adding the ptep, but junk pte likely to fail the
      tests for page_remove_rmap.
      
      Eventually the child exits, the page table is freed and try_to_unmap_one
      oopses on null ptep_to_mm (but in a kernel with rss limiting, usually
      page_referenced hits the null ptep_to_mm first).
      
      This took me days and days to unravel!  Big thanks to Matthieu for
      reporting it with a good test case.
