      [PATCH] MD - Fix two bugs that would cause sync_sbs to Oops · d1cde62a
      Neil Brown authored
      Sync_sbs tries to access the ->sb for the first rdev of an mddev.
      This can oops as the wrong arg is given to list_entry, and also
      if a define was faound to be failed, as failed devices have their ->sb
      removed.  But that removal isn't necessary, so now an rdev will always
      have an ->sb.

      [PATCH] type safe(r) list_entry repacement: container_of · ec4f2142
      Neil Brown authored
      Define container_of which cast from member to struct with some type checking.
      
      This is much like list_entry but is cearly for things other than lists.
      
      List_entry now uses container_of.

      [PATCH] shm_destroy lock hang · 960d4b34
      Hugh Dickins authored
      Martin Schwidefsky <schwidefsky@de.ibm.com> reported "Bug with shared
      memory" to LKML 14 May: hang due to schedule in truncate_list_pages
      called from .... shm_destroy holding shm_lock spinlock.  shm_destroy
      needs that lock for shm_rmid, but it can be safely unlocked once link
      from id to shp has been removed.

      [PATCH] IDE-101 · 02114f71
      Martin Dalecki authored
      Here is a quick fix.  I would like to synchronize with the irq handler
      changes as well.  Becouse right now I know that preemption is killing
      the disk subsystem when moving data between disks using different
      request queues...  In esp.  It get's me in to do_request() with a queue
      in unplugged state.  (Not everything is my fault, after all :-).

      [PATCH] irqlock patch 2.5.27-H6 · a6efb709
      Ingo Molnar authored
       - init thread needs to have preempt_count of 1 until sched_init().
         (William Lee Irwin III)
       - clean up the irq-mask macros. (Linus)
       - add barrier() to irq_enter() and irq_exit(). (based on Oleg Nesterov's
         comment.)
       - move the irqs-off check into preempt_schedule() and remove
         CONFIG_DEBUG_IRQ_SCHEDULE.
       - remove spin_unlock_no_resched() and comment the affected places more
         agressively.
       - slab.c needs to spin_unlock_no_resched(), instead of spin_unlock(). (It
         also has to check for preemption in the right spot.) This should fix
         the memory corruption.
       - irq_exit() needs to run softirqs if interrupts not active - in the
         previous patch it ran them when preempt_count() was 0, which is
         incorrect.
       - spinlock macros are updated to enable preemption after enabling
         interrupts. Besides avoiding false positive warnings, this also
       - fork.c has to call scheduler_tick() with preemption disabled -
         otherwise scheduler_tick()'s spin_unlock can preempt!
       - irqs_disabled() macro introduced.
       - [ all other local_irq_enable() or sti instances conditional on
           CONFIG_DEBUG_IRQ_SCHEDULE are to fix false positive warnings. ]
       - fix buggy in_softirq(). Fortunately the bug made the test broader,
         which didnt result in algorithmical breakage, just suboptimal
         performance.
       - move do_softirq() processing into irq_exit() => this also fixes the
         softirq processing bugs present in apic.c IRQ handlers that did not
         test for softirqs after irq_exit().
       - simplify local_bh_enable().
