      [PATCH] 2.5.6-pre1 IDE cleanup 10 · f0a86f5a
      Martin Dalecki authored
      This is finishing the cleanup parts already started in ide-clean-9.
      
      It kills the ide_register_module() and ide_unregister_module() as well
      as associated idiosyncracies alltogether. It turns out
      that this patch is actually fixing a bug which was present in the
      driver before: the sub-module initialization functions where called
      at least twice - which is an abundance.
      
      Tough there is a bit of global namespace pollution caused by this
      patch - but I'm aware of it and will fix it just a bit later.
      (The terminology used inside the IDE code is anyway nothing common
      else in the linux universum...)
      
      The next targets will be:
      
      1. Code obfuscation by "wrappers" around generic BIO level functions.
      
      2. ide_hwgroup_t - which is only used to serialize multiple
      discs on the same interrupt and similar. This is however a tough one.
      
      3. There is a plenty of code waste in the chipset drivers, where there
      is baroque informative code for the proc file system for static stuff,
      which in fact belongs just to syslog(). In fact the default RedHat
      distribution kernel is killing this gratitious abuse of the /proc
      concept since a long long time...
      
      I'm still awaiting the day of /proc/GPL, where GPL contains the
      full text of it...

      Shrink icache more aggressively - if we free the dentries, · 38b20d21

      go ahead and free the inodes too, don't try to age them any
      more (the aging has been done on a dentry level).

      [PATCH] 2.5 scsi changes : qlogicfas.c fixed (resend) · dde3d25b
      Brett Pemberton authored
      This patch allows my qlogic pcmcia scsi card to compile again, as broken
      by the recent scsi layer changes. 
      
      Despite davem's apparent suggestion that it'd be better to rewrite the
      driver, i'd rather not _just_ right now :)

      [PATCH] MTD update. · 5a22d00c
      Dave Jones authored
      Numerous bugfixes brought forward from 2.4. I added some quick bio fixes
      to mtdblock.c, which seemed to work for me whilst testing JFFS2 changes.

      [PATCH] updates. · 34a7eea9
      Dave Jones authored
      Forward ports from 2.4, Various janitor bits, and some fixes by me to
      make the thing work again in 2.5.  I munged the MTDRAM driver to work
      also (seperate patch to follow), and it seems to work.
      
      David Woodhouse gave this the once over, and approved the changes.
      Complete changelog below:
      
      o   Don't create two slabcaches with the same name.
      o   Don't corrupt eraseblock lists on mount
      o   Don't mark nodes obsolete during mount
      o   __attribute__((packed)) on the node definitions.
      o   Fix up() without down() in jffs2_readdir().
      o   Fix duplicate version number usage - s/highest_version++/++highest_version/
      o   Fix (i.e. implement) mtime/ctime on directories.
          maybe too busy with the bk stuff
      o   Don't allow hardlinks of directories.
      o   s/(mode&S_IFMT)==S_IFLNK/S_ISLNK(mode)/ et al to keep Al happy.
      o   Fix for garbage-collection of holes, where we used to write nodes out
          with csize/dsize swapped. Workarounds for existing such brokenness.
      o   Improve wear levelling by rotating node lists on mount, to avoid starting
           at one end of the flash every time.
      o   Remember to get internal inode-semaphore on symlink operations.

      [PATCH] PATCH 15/16: NFSD: TCP: Limit number of active tcp connections to an RPC service · afdb4fa2
      Neil Brown authored
      Limit number of active tcp connections to an RPC service
      
      If a connection comes in and that results in number of
      connections being more than 5 times the number of threads,
      then we close a connection.
      
      We randomly drop with the oldest or the newest connection.
      
      Thus if we are flooded with connection requests, some will
      get in and hopefully stay long enough to service at least one request.

      [PATCH] PATCH 14/16: NFSD: TCP: Declare max response sizes for NFS and NLM · 4e2f6bfe
      Neil Brown authored
      Declare response sizes for nfs/lockd requests
      
      This allows sndbuf reservation to be more accurate.
      
      For lockd we just say "0" for now, meaning assume the max.
      This could be improved, but it isn't critical.

      [PATCH] PATCH 13/16: NFSD: TCP: Reserve space on sndbuf so we never block when writing · a87d7392
      Neil Brown authored
      Make sure there is alway adequate sndbuf space for replies.
      
      We keep track of how much space might be needed for replies
      and never dequeue a request unless there is adequate space
      for a maximal reply.  We assume each request will generate a maximal
      sized reply until the request is partly decoded.
      Each RPC program/procedure can specify the maximum size
      of a reply to the precedure (though they don't yet).
      
      The wspace callback is used to enqueue sockets that may be waiting
      for sndbuf space to become available.
      
      As there should always be enough buffer space to the full
      reply, the only reason that sock_sendmsg could block is due
      to a kmalloc delay.  As this is likely to be fairly quick (and if
      it isn't the server is clagged anyway) we remove the MSG_DONTWAIT
      flag, but set a 30 second timeout on waiting.  If the wait
      ever times out, we close the connection.  If it doesn't we can
      be sure that we did a complete write.
      
      
      When a request completes, we make sure that the space
      used for the reply does not exceed the space reserved.  This
      is an internal consistancy check.
      
      This patchs sets the sndbuf and rcvbuf sizes for all sockets
      used for rpc service.  This size if dependant on the servers bufsize (S) and
      partially on the number of threads (N).
      
      For UDP
          sndbuf == 5*S
          rcvbuf == (N+2)*S
      for TCP
          sndbuf == N*S
          rcvbuf == 3*S
      
      see code for rationale (in comments).

      [PATCH] PATCH 12/16: NFSD: TCP: Close idle TCP connections · cbf593fc
      Neil Brown authored
      Close idle rpc/tcp sockets
      
      We split the list of sv_allsocks into two, one
      of permanent sockets (udp, tcp listener) and one
      of temporary sockets (tcp data).
      
      Whenever we complete a successful receive on a temp socket,
      it gets pushed to the end of the list.
      
      Whenever a thread wants to do something, it first checks if
      the oldest temp socket has not has a receive for 6 mintutes
      (should possibly be configurable).  It so, we simulate
      a close.
      
      Finally we make sure that threads wake up every few minutes
      so that if the server is completely idle, all temp
      sockets will get closed.

      [PATCH] PATCH 11/16: NFSD: TCP: close bad connections · 84e9f22a
      Neil Brown authored
      Detect and close tcp connections that we cannot work with.
      
      If an rpc fragment that arrives on a tcp connection
      is non-terminal or too large for our buffer, then we
      have to close the connection.
      Also, if a write fails on a tcp connection, we close
      the connection.

      [PATCH] PATCH 10/16: NFSD: TCP: rationalise locking in RPC server routines · 294d77d9
      Neil Brown authored
      Tidy up SMP locking for svc_sock
      
      sk_lock is not necessary and is now removed.
      The only things that were happening under sk_lock but
      not the more global sv_lock were testing and setting
      some of the flags: sk_busy, sk_conn, sk_data etc.
      
      These have been changed to bits in a flags word which are atomically
      set and tested.
      
      Also, by establishing some simple rules about that must
      be done after setting these flags, the locking is not needed.
      
      With this patch sk_conn and sk_data are now flags, not counts (sk_data
      was already a flag for udp).  They are set if there might be
      a connection or data, and only clear when we are sure there aren't
      (or when we are about to check if there is).
      
      svc_sock_accepted becomes identical to svc_sock_recieved and
      so is discarded in favour of the latter.
      
      sk_rqstp was never used and is now gone.
