      [PATCH] Rename bitmap_snprintf() and cpumask_snprintf() to *_scnprintf() · e9dc2e51
      Andrew Morton authored
      From: Joe Korty <joe.korty@ccur.com>
      
      Rename bitmap_snprintf() to bitmap_scnprintf() and cpumask_snprintf() to
      cpumask_scnprintf(), as these functions now belong to the scnprintf family
      of functions.

      [PATCH] MCE fixes and cleanups · 3aa6ed84
      Andrew Morton authored
      Andi notes that the
      
      	smp_call_function(foo);
      	foo();
      
      in there is incorrect on preemptible kernels.
      
      Fix that by using on_each_cpu(), which takes care of such things.
      
      Also, remove the open-coded timer from here.  We have
      schedule_delayed_work().
      
      And remove the `timerset' variable, which doesn't do anything.

      [PATCH] Fix printk level on non fatal MCEs · 2d943d44
      Andrew Morton authored
      From: Andi Kleen <ak@suse.de>
      
      For various reasons non fatal Machine Checks can happen on Athlons (e.g.
      we have reports that laptops like to trigger them on suspend/resume)
      
      They are not necessarily fatal and often only minor hardware glitches.
      
      But what's annoying is that they're KERN_EMERG and pollute your console and
      scare the user into writing confused kernel bug reports.
      
      This patch just replaces the KERN_EMERGs with KERN_INFO for now.  Longer
      term I think it would be better to log this stuff into a separate log.

      [PATCH] dm: drop BIO_SEG_VALID bit · d4634c58
      Andrew Morton authored
      From: Joe Thornber <thornber@redhat.com>
      
      I just noticed that bio_clone copies the BIO_SEG_VALID bit from the original
      bio when it was set.  When we modify bi_idx or bi_vcnt afterwards the segment
      counts are invalid and the bit must be dropped (though it is fairly unlikely
      that it has already been set).  [Christophe Saout]

      [PATCH] md: Allow partitioning of MD devices. · 1797a796
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      With this patch, md used two major numbers for arrays.
      
      One Major is number 9 with name 'md' have unpartitioned md arrays, one per
      minor number.
      
      The other Major is allocated dynamically with name 'mdp' and had on array for
      every 64 minors, allowing for upto 63 partitions.
      
      The arrays under one major are completely separate from the arrays under the
      other.
      
      The preferred name for devices with the new major are of the form:
      
        /dev/md/d1p3  # partion 3 of device 1 - minor 67
      
      When a paritioned md device is assembled, the partitions are not recognised
      until after the whole-array device is opened again.  A future version of
      mdadm will perform this open so that the need will be transparent.

      [PATCH] md: Dynamically limit size of bio requests used for raid1 resync · 5077fef0
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      Currently raid1 uses PAGE_SIZE read/write requests for resync, as it doesn't
      know how to honour per-device restrictions.  This patch uses to bio_add_page
      to honour those restrictions and ups the limit on request size to 64K.  This
      has a measurable impact on rebuild speed (25M/s -> 60M/s)

      [PATCH] md: Avoid unnecessary bio allocation during raid1 resync · 89654f5b
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      For each resync request, we allocate a "r1_bio" which has a bio "master_bio"
      attached that goes largely unused.  We also allocate a read_bio which is
      used.  This patch removes the read_bio and just uses the master_bio instead.
      
      This fixes a bug wherein bi_bdev of the master_bio wasn't being set, but was
      being used.
      
      We also introduce a new "sectors" field into the r1_bio as we can no-longer
      rely in master_bio->bi_sectors.

      [PATCH] md: Remove some un-needed fields from r1bio_s · d0d464b1
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      next_r1 is never used, so it can just go.
      
      read_bio isn't needed as we can easily use one of the pointers in the
      write_bios array - write_bios[->read_disk].  So rename "write_bios" to "bios"
      and store the pointer to the read bio in there.

      [PATCH] md: Discard the cmd field from r1_bio structure · ebf7768e
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      The only time it is really needed is to differentiate a retry-on-fail from a
      write-after-read-for-resync request to raid1d.  So we use a bit in 'state'
      for that.

      [PATCH] md: Split read and write end_request handlers · c1dd448e
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      Instead of having a single end_request handler that must determine whether it
      was a read or a write request, we have two separate handlers, which makes
      each of them easier to follow.

      [PATCH] md: Print "deprecated" warning when START_ARRAY is used. · a2c4e506
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      The "START_ARRAY" ioctl depends on major/minor numbers (as stored in the raid
      superblock) are stable over reboots, which is increasingly untrue.
      
      There are better ways to start an array (e.g.  with mdadm) so we mark the
      ioctl as deprecated for 2.6, and will remove it in 2.7.

      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      There is no way to return an error from a cache init routine, so instead we
      make sure to pre-allocate the memory needed, and free it after the lookup
      if the lookup failed.

      [PATCH] kNFSd: Allow sunrpc/svc cache init function to modify the "key" · 9417bd87
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      When adding a item to a sunrpc/svc cache that contains kmalloced data it is
      usefully to move the malloced data out of the key object into the new cache
      object rather than copying (as then we would need to cope with kmalloc
      failure and such).  This means modifying the original.
      
      If the kmalloced data forms part of the key, then we must not move the data
      out until after the key isn't needed any more.  So this patch moves the
      call to "INIT" on a new item (which fills in the key) to *after* the item
      has been found (or not), and also makes sure we only call the HASH function
      once.
      
      Thanks to "J.  Bruce Fields" <bfields@fieldses.org>

      [PATCH] #if versus #ifdef cleanup · c65febbb

      From: Valdis.Kletnieks@vt.edu
      
      15 changes of #if to #ifdef and 2 places CONFIG_FOO should be
      defined(CONFIG_FOO).  This gets rid of spurious warnings if you build with
      "-Wundef" so you get a warning if you have a preprocessor command like:
      
      #if CONFIG_ETRAX_DS1302_RSTBIT == 27
      
      and you'll be told if it's substituting a zero rather than silent
      weirdness and unexpected code generation.

      [PATCH] Enable coredumps > 2GB · 95b387a4
      Andrew Morton authored
      From: Andi Kleen <ak@muc.de>
      
      Some x86-64 users were complaining that coredumps >2GB don't work.
      
      This will enable large coredump for everybody.  Apparently the 32bit
      gdb/binutils cannot handle them, but I hear the binutils people are working
      on fixing that.  I doubt it will harm people - unreadable coredumps are not
      worse than no coredump and it won't make any difference in space usage if
      you get a 1.99GB or a 2.5GB coredump.  So just enable it unconditionally.
      If it should be really a problem for 32bit the rlimit defaults in
      resource.h could be changed.
      
      For file systems that don't support O_LARGEFILE you should just get an
      truncated coredumps for big address spaces.

      - use struct nameidata in devfs_d_revalidate_wait to detect when it is

        prevents both deadlock with devfs_lookup by allowing it to drop i_sem
        consistently and oops in d_instantiate by ensuring that it always runs
        protected
      
      - remove dead code that deals with major number allocation.  The only
        remaining user was devfs itself and patch changes it to
      
      - use register_chardev to get device number for internal /dev/.devfsd and
        /dev/.statd.
      
      - remove dead auto allocation flag as well
      
      - remove code that does module get on dev open - it is handled by fops_get.
         Use init_special_inode consistently

      [PATCH] snprintf fixes · 01d1a791
      Andrew Morton authored
      From: Juergen Quade <quade@hsnr.de>
      
      Lots of places in the kernel are using [v]snprintf wrongly: they assume it
      returns the number of characters copied.  It doesn't.  It returns the
      number of characters which _would_ have been copied had the buffer not been
      filled up.
      
      So create new functions vscnprintf() and scnprintf() which have the
      expected (sane) semaptics, and migrate callers over to using them.
