      [PATCH] ext3: move lock_kernel() down into the JBD layer. · 3307fbd1
      Andrew Morton authored
      This is the start of the ext3 scalability rework.  It basically comes in two
      halves:
      
      - ext3 BKL/lock_super removal and scalable inode/block allocators
      
      - JBD locking rework.
      
      The ext3 scalability work was completed a couple of months ago.
      
      The JBD rework has been stable for a couple of weeks now.  My gut feeling is
      that there should be one, maybe two bugs left in it, but no problems have
      been discovered...
      
      
      Performance-wise, throughput is increased by up to 2x on dual CPU.  10x on
      16-way has been measured.  Given that current ext3 is able to chew two whole
      CPUs spinning on locks on a 4-way, that wasn't especially suprising.
      
      These patches were prepared by Alex Tomas <bzzz@tmi.comex.ru> and myself.
      
      
      First patch: ext3 lock_kernel() removal.
      
      The only reason why ext3 takes lock_kernel() is because it is requires by the
      JBD API.
      
      The patch removes the lock_kernels() from ext3 and pushes them down into JBD
      itself.
