      [PATCH] (3/5) sane procfs/dcache interaction · 00306333
      Alexander Viro authored
       - sane dentry retention.  Namely, we don't kill /proc/<pid> dentries at the
         first opportunity (as the current tree does).  Instead we do the following:
      	* ->d_delete() kills it only if process is already dead.
      	* all ->lookup() in proc/base.c end with checking if process is still
      	  alive and unhash if it isn't.
      	* proc_pid_lookup() (lookup for /proc/<pid>) caches reference to dentry
      	  in task_struct.  It's _not_ counted in ->d_count.
      	* ->d_iput() resets said reference to NULL.
      	* release_task() (burying a zombie) checks if there is a cached
      	  reference and if there is - shrinks the subtree.
      	* tasklist_lock is used for exclusion.
         That way we are guaranteed that after release_task() all dentries in
         /proc/<pid> will go away as soon as possible; OTOH, before release_task()
         we have normal retention policy - they go away under memory pressure with
         the same rules as for dentries on any other fs.

      [PATCH] simple preemption debug check · 6a1a68c8
      Robert Love authored
      This simple check was first suggested by Andrew Morton.  Pretty basic -
      whines if a task exits with a nonzero preempt_count value.
      
      I put an identical check in the 2.4 preempt-kernel patch and - sure
      enough - it was found that XFS essentially disables preemption as it
      destroys data structures containing locks without first unlocking.  The
      SGI folks are working on that.
      
      Anyhow, its a quick and clean solution to debugging potential problems.
      Patch is against 2.5.7, please apply.

      You are right, it did.  I removed all the sched.h dependencies and this
      reduced the size of the patch greatly.  I now use current_thread_info()
      and none of the header or include hackery from before.  I've tested this
      with and without preemption enabled with success.
      
      I appreciate your help with this.
      
      Again, this is a minimal i386-only patch.  I have other arches,
      documentation, etc.  Patch against 2.5.4-pre5.  Enjoy,

      [PATCH] thread information block · 9b10610a
      David Howells authored
      syscall latency improvement
      
       * There's now an asm/thread_info.h header file with the basic structure
         def and asm offsets in it.
      
       * There's now a linux/thread_info.h header file which includes the asm
         version and wraps some bitops calls to make convenience functions for
         accessing the low-level flags. 
      
       * The task_struct has had some fields removed (and some flags), and has
         acquired a pointer to the thread_info struct.
      
       * task_struct's are now allocated on slabs in kernel/fork.c, whereas
         thread_info structs are allocated at the bottom of the stack pages.
      
       * Some more convenience functions are provided at the end of linux/sched.h to
         access flags in other tasks (these are here because they need to access the
         task_struct).
