      dcache: use a dispose list in select_parent · b48f03b3
      Dave Chinner authored
      
      
      select_parent currently abuses the dentry cache LRU to provide
      cleanup features for child dentries that need to be freed. It moves
      them to the tail of the LRU, then tells shrink_dcache_parent() to
      calls __shrink_dcache_sb to unconditionally move them to a dispose
      list (as DCACHE_REFERENCED is ignored). __shrink_dcache_sb() has to
      relock the dentries to move them off the LRU onto the dispose list,
      but otherwise does not touch the dentries that select_parent() moved
      to the tail of the LRU. It then passses the dispose list to
      shrink_dentry_list() which tries to free the dentries.
      
      IOWs, the use of __shrink_dcache_sb() is superfluous - we can build
      exactly the same list of dentries for disposal directly in
      select_parent() and call shrink_dentry_list() instead of calling
      __shrink_dcache_sb() to do that. This means that we avoid long holds
      on the lru lock walking the LRU moving dentries to the dispose list
      We also avoid the need to relock each dentry just to move it off the
      LRU, reducing the numebr of times we lock each dentry to dispose of
      them in shrink_dcache_parent() from 3 to 2 times.
      
      Further, we remove one of the two callers of __shrink_dcache_sb().
      This also means that __shrink_dcache_sb can be moved into back into
      prune_dcache_sb() and we no longer have to handle referenced
      dentries conditionally, simplifying the code.

      tracing/mm: Move include of trace/events/kmem.h out of header into slab.c · 4dee6b64
      Steven Rostedt authored
      Including trace/events/*.h TRACE_EVENT() macro headers in other headers
      can cause strange side effects if another trace/event/*.h header
      includes that header.  Having trace/events/kmem.h inside slab_def.h
      caused a compile error in sparc64 when changes were done to some header
      files.  Moving the kmem.h trace header out of slab.h and into slab.c
      fixes the problem.
      
      Note, both slub.c and slob.c already include the trace/events/kmem.h
      file. Only slab.c had it missing.

      igmp: Avoid zero delay when receiving odd mixture of IGMP queries · a8c1f65c
      Ben Hutchings authored
      Commit 5b7c8406
      
       ('ipv4: correct IGMP
      behavior on v3 query during v2-compatibility mode') added yet another
      case for query parsing, which can result in max_delay = 0.  Substitute
      a value of 1, as in the usual v3 case.
