      [PATCH] Fix NFS locking over TCP · 23288376
      Trond Myklebust authored
      The 2.5.x RPC code is currently broken in that it demands that all
      tasks that call xprt_create_proto() in order to open a TCP socket must
      have CAP_NET_BIND_SERVICE capabilities, and must bind to a privileged
      port.
      
      This breaks the NLM locking code and its use of the call_bind() RPC
      portmapper lookup feature.
      
      This patch allows the built-in portmapper client to use unbound TCP
      sockets if the user does not have the necessary capabilities.

      [PATCH] A basic NFSv4 client for 2.5.x · 63a5ba42
      Trond Myklebust authored
      This is a nontrivial change to the NFS client.
      
      In this patch, we finish modifying the async READ path so that it is
      version-agnostic.  We define a new nfs_rpc_op ->setup_read(), and move
      the v2- and v3-specific code in nfs_read_rpcsetup() there.  We also
      have to change nfs_readpage() result so that the 'count' of bytes
      read is a parameter.  The extra parameter means that it can no longer
      be ->tk_exit().  Instead, it is called from a version-specific ->tk_exit()
      routine which is set in ->read_setup().
      
      The upshot of all this is that the version-specific part of the
      async READ path has been encapsulated in a new nfs_rpc_op
      ->read_setup(), and NFSv4 can share the logic for asynchronous
      READ's with NFSv2 and v3.

      [PATCH] A basic NFSv4 client for 2.5.x · aa1e1176
      Trond Myklebust authored
      This is a nontrivial change to the NFS client.
      
      Synchronous READ operations are currently done via the ->read() nfs_rpc_op.
      Therefore, the synchronous READ path can easily be adapted for NFSv4.  On
      the other hand, the asynchronous READ path contains several NFSv3-specific
      features, which make it difficult to adapt for NFSv4.
      
      In this patch and the next, we modify the async READ path to be
      version-agnostic.  This patch just changes the 'struct nfs_read_data'
      so that the v2- and v3-specific parts are moved into a private area,
      with room for a v4-specific part in parallel.  None of the logic is
      changed.

      If the NFS_ATTR_FATTR_V4 flag is set, use the NFSv3 convention for

      [PATCH] A basic NFSv4 client for 2.5.x · 3aeba064
      Trond Myklebust authored
      This is a nontrivial change to the NFS client.
      
      NFSv4 defines a new file attribute, change_attr.  This is a per-file
      opaque quantity returned by the server, whose value is required to
      change whenever the file is modified.  If it exists, we want to use
      it for all cache consistency checks in nfs_refresh_inode().  Some
      operations also return a "pre-operation" value of the change_attr;
      we want to take this into account too.
      
      First, define flags
        NFS_ATTR_FATTR_V4 - indicates that the 'struct nfs_fattr' is an
                            NFSv4 fattr, so the change_attr field is valid
        NFS_ATTR_PRE_CHANGE - indicates that the server returned a pre-operation
                            change_attr, so the pre_change_attr field is valid
      
      Second, change nfs_refresh_inode() so that the caches are invalidated
      if there is a change_attr mismatch.  Exception: If the pre_change_attr
      tells us that the mismatch was caused by our operation, then do not
      invalidate the caches.
      
      This patch should leave the logic in nfs_refresh_inode() unchanged
      if neither of the new flags are set.

      [PATCH] A basic NFSv4 client for 2.5.x · 62d86355
      Trond Myklebust authored
      This patch changes the interface of the ->setattr() nfs_rpc_op
      so that its first argument is a dentry instead of an inode.
      
      [Explanation: The dentry is required because in NFSv4, we may
       need to OPEN the file before doing the SETATTR.  (This is
       required if the file size is changed as part of the setattr.)
       Opening the file requires making use of the containing
       directory's inode.]

      This patch changes the interface of the ->readdir() nfs_rpc_op
      so that its first argument is a dentry instead of an inode.
      
      [Explanation: The dentry is required because in NFSv4, we need
       to make use of the _parent_ directory's inode.  This is because
       NFSv4 servers no longer return an entry for ".." in the READDIR
       response, so the client kernel needs to fake this entry, inode
       number and all.]

      [PATCH] linux-2.5.41_cyclone-timer_B2 · 21872250
      John Stultz authored
              In order to demonstrate how new time-sources are added to my
      timer-changes patch. Here is my current version of my cyclone-timer
      patch for 2.5.41. This uses the infrastructure set up in the
      timer-changes_A4 patch set to add the cyclone counter (found on IBM
      Summit Based hardware) as a time-source.
      
              The current code is not enabled as it also depends on James
      Cleverdon's 2.5 summit patch, however it illustrates how cleanly new
      time-sources can be added.

      [PATCH] linux-2.5.41_timer-changes_A4 (1/3 - infrastructure) · c710b958
      John Stultz authored
              The i386 time.c code is turning into a mess. We've got multiple
      functions that do the same thing, only with different hardware, all
      surrounded #ifdefs and even more difficult to follow #ifndefs. George
      Anzinger is introducing a new ACPIpm time source, I'm going to attempt
      to add the cyclone counter as a time source, and in the future there
      will be HPET to deal with. These will not go in cleanly together as
      things are now.
      
              Inspired by suggestions from Alan, this collection of patches
      tries to clean up time.c by breaking out the PIT and TSC specific parts
      into their own files. Additionally the patch creates an abstract
      interface to use these existing time soruces, as well as make it easier
      to add future time sources.
      
              It introduces "struct timer_ops" which gives the time code a
      clear interface to use these different time sources. It also allows for
      clearer conditional compilation of these various time sources.
      
              This first patch (part 1 of 3) provides the infrastructure
      needed via the timer_ops structure, as well as the select_timer()
      function for choosing the best available timer.

      [PATCH] make readv/writev return 0 for 0 segments · 6a839d30
      Andrew Morton authored
      Should resolve an ongoing fiasco concerning what we should return to
      userspace if they do a readv or writev of zero segments.
      
      SuS is ambiguous, but implies EINVAL.  We're currently returning
      EINVAL, but 2.4 returns zero.

      [PATCH] remove the sched_yield from the ext3 fsync path · 522864f4
      Andrew Morton authored
      The changed sched_yield() semantics have made ext3's transaction
      batching terribly slow.
      
      Apparently a schedule() fixes that, although it probably breaks
      transaction batching.
      
      This patch largely fixes my complaints about the new scheduler being
      extremely sluggish to interactive applications.  Evidently those
      applications were calling fsync() and were spending extremely long
      periods in sched_yield().

      [PATCH] move_one_page atomicity fix · d8f299c2
      Andrew Morton authored
      The atomicicty fix for move_one_page() was not quite right.
      
      We only do the page_table_present() test if CONFIG_HIGHPTE=y.  Which is
      fine, but even with CONFIG_HIGHPTE=n, the pte mapping functions still
      do an inc_preempt_count() due to their unconditional kmap_atomic().  So
      we get a might_sleep() warning.
      
      The warning is actually bogus, because those pte's are always in
      direct-mapped memory.
      
      So hm.  Three fixes suggest themselves:
      
      1: Run the page_table_present() test if CONFIG_HIGHMEM.
      
         Rejected: penalises non-pte_highmem setups
      
      2: Make kmap_atomic() not do inc_preempt_count() is the page was
         direct mapped.
      
         Rejected: I don't think we want kmap_atomic side effects to be
         varying according to the page which was passed.
      
      3: Change the pte mapping functions so they don't run kmap_atomic at
         all if CONFIG_HIGHPTE=n
      
         This is what I did.  And guess what?  For CONFIG_HIGHMEM=y,
         CONFIG_HIGHPTE=n this patch shrinks the kernel by 5 kbytes.  Because
         kmap_atomic is inlined.
      
         The lesson: we do way too much damn inlining.

      2 bug fixes for scsi pass through
      
      When talking directly to scsi devices, the driver would

      [PATCH] ips driver 4/6 · 20081964
      David Jeffery authored
      This is by far the biggest patch.  It is a rewrite of the
      driver's horrid locking.  In addition to the host_lock,
      the driver used to have 4 other locks per adapter!
      It had a redundant ha_lock and a lock for each of 3
      queues.  In a few places it also played with atomic bit
      setting. And almost all of it was useless as the
      host_lock was already held.
      
      This patch cleans up this locking nightmare.  The driver
      now uses the host_lock exclusively.  Only a few places
      needed to add calls to lock the host_lock.  Most of
      this patch is deletion of useless extra locking.

      A new function ips_abort_init() is created
      and consolidates some repeated code that is
      used if there is an error during initialization
      of the adapter.

      [PATCH] ips driver 1/6 · ab804805
      David Jeffery authored
      This removes several unused header includes and allows
      the driver to compile by no longer trying to include
      <linux/tqueue.h> . You may have already gotten a patch
      to remove tqueue.h from someone else.
      
      This patch also corrects the spelling of my last name
      in the MAINTAINERS file.  You'd think I'd be used to
      seeing it spelled wrong by now.
