      [PATCH] ppc64: move kmem_bufctl_t inside #ifndef __ASSEMBLY__ · 1ba3a31f
      Paul Mackerras authored
      When the kmem_bufctl_t typedef got added to include/asm-ppc64/types.h,
      it got added outside the #ifndef __ASSEMBLY__ section, causing
      assembler errors.  This patch, from David Gibson, moves it inside the
      #ifndef __ASSEMBLY__ region.

      [PATCH] raid locking fix. · 26c78a95
      Andrew Morton authored
      From: Neil Brown <neilb@cse.unsw.edu.au>
      
      Fix bug #2661
      
      Raid currently calls ->unplug_fn under spin_lock_irqsave(), but unplug_fns
      can sleep.
      
      
      After a morning of scratching my head and trying to come up with some that
      does less locking, the following is the best I can come up with.  I'm not
      proud of it but it should work.
      
      If I move "nr_pending" out or rdev into the per-personality structures
      (e.g.  mirror_info), and if I had "atomic_inc_if_nonzero" I could do with
      without locking so much, but random atomic* functions don't seem trivial

      [PATCH] use-before-uninitialized value in ext3(2)_find_ goal · 83ee50f5
      Andrew Morton authored
      From: Mingming Cao <cmm@us.ibm.com>
      
      There is a uninitialized goal value being referenced in both ext3 and ext2
      find goal block functions (ext3_find_goal() and ext2_find_goal()).
      
      In the non-sequential write case, these functions check the goal value(non
      zero) before calling ext3(2)_find_near() to find the goal block to
      allocate.
      
      Since the goal value is uninitialized(non zero), the ext3(2)_find_near() is
      never being called in the non-sequential write, thus ext3(2)_find_goal()
      failed to guide a goal block in the random write case.
      
      ext3(2)_new_block() takes the junk goal value and will turn it to goal 0
      since it's normally beyond the filesystem block number limit.  The fix is
      trivial.

      [PATCH] Fix overzealous use of online cpu iterators · 2cb2f31f
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      The IA64 hotplug CPU merge seems to have included some core changes: in
      particular the recalc_bh_state() needs to sum for all (including offline)
      cpus, since we don't empty the counters on CPU down.  The totals printed by
      /proc/stat (the first loop) should include offline cpus, too (apparently
      printing out the per-cpu lines for offline cpus confuses top).

      [PATCH] VFS cache sizing fix for small machines · 227d8064
      Andrew Morton authored
      From: Matt Mackall <mpm@selenic.com>
      
      Doing the algebra:
      
      c = (a - b) * 3/2
      a' = a - c = a - 3/2(a - b) = (2a - 3a + 3b)/2 = (3b - a)/2
      a' >= 0
      3b - a >= 0
      3b >= a
      b >= a/3
      nr_free_pages() >= mempages/3
      
      We can indeed get into trouble if we try to load a large kernel on a very
      small box (ie kernel reserves more than 2/3 of usable memory).  Surprisingly I
      haven't hit this, but here's a fix.

      [PATCH] kNFSd: Remove check on number of threads waiting on user-space. · 95321936
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      From: "J. Bruce Fields" <bfields@fieldses.org>
      
      Currently we are counting the number of threads already asleep and returning
      an immediate NFS4ERR_DELAY (==JUKEBOX) error if more than half are already
      asleep.
      
      This patch removes that logic, so instead we only return NFS4ERR_DELAY if an
      upcall times out (if it takes more than a second to return).
      
      With the thread counting there is the risk that even when all the relevant
      subsystems are responsive, the client may still see occasional NFS4ERR_DELAY
      returns just because, by coincidence, several upcalls were initiated at the
      same time.  I expect clients will delay several seconds before retrying after
      NFS4ERR_DELAY, so this will be quite noticeable to users.  Sporadic long
      delays like this are likely to lead users to suspect a problem somewhere, when
      in fact there is none.
      
      The current scheme ensures that we can still process requests not depending on
      upcalls, even when all threads would otherwise be tied up waiting on upcalls. 
      However, this is not something that should happen under normal circumstances;
      if a server spends a significant portion of its time with all threads waiting
      for upcalls, this a sign that something is seriously wrong.
      
      In such a circumstance (e.g., an ldap server dies), we can, at least, bound
      the waiting time to a second without the need for counting threads.
      
      In short, removing the thread-counting will allow us to behave predictably
      when things are working, while still allowing some progress when they don't.
      
      It would be a worthwhile project to measure the amount of time threads spend
      waiting for upcalls (or for reads, for that matter); if a significant portion
      of the time they spend handling requests is spent sleeping, then there's an
      opportunity to improve nfsd performance: if we can break the one-to-one
      mapping between requests and threads, then we can lower the number of threads
      required to keep the nfs server busy.
      
      However, both the currently available options for doing this are problematic:
      returning JUKEBOX/DELAY errors at random times will lead to unpredictable
      performance, and saving a copy of the request to be processed from scratch
      again later is wasteful and makes it difficult to provide correct semantics,
      especially in the NFSv4 case.
      
      So for now I believe waits with short timeouts are the best option.

      From: "J. Bruce Fields" <bfields@fieldses.org>
      
      1 second should be plenty of time; if we're going to take longer than that
      it's probably better just to return NFS4ERR_DELAY and let the client retry
      anyway.

      [PATCH] kNFSd: Improve idmapper behaviour on failure. · 74d88830

      From: "J. Bruce Fields" <bfields@fieldses.org>
      
      Slightly better behavior on failed mapping (which may happen either because
      idmapd is not running, or because there it has told us it doesn't know the
      mapping.):
      
      	on name->id (setattr), return BADNAME.  (I used ESRCH to
      		communicate BADNAME, just because it was the first error in
      		include/asm-generic/errno-base.h that had something to
      		do with nonexistance of something, and that we weren't
      		already using.)
      
      	id->name (getattr), return a string representation of the numerical
      		id.  This is probably useless to the client, especially
      		since we're unlikely to accept such a string on a setattr,
      		but perhaps some client will find it mildly helpful.

      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      nfsd_cross_mnt can release the reference to the passed svc_export structure
