      GFS2: inline __gfs2_glock_schedule_for_reclaim · 4abb6ad9
      Bob Peterson authored
      Since function gfs2_glock_schedule_for_reclaim is only two
      significant lines, we can eliminate it, simplifying the code
      and making it more readable.

      GFS2: change function gfs2_direct_IO to use a normal gfs2_glock_dq · 8e711e10
      Bob Peterson authored
      This patch changes function gfs2_direct_IO so that it uses a normal
      call to gfs2_glock_dq rather than a call to a multiple-dq of one item.

      GFS2: rbm code cleanup · 8d8b752a
      Bob Peterson authored
      This patch fixes a few small rbm related things. First, it fixes
      a corner case where the rbm needs to switch bitmaps and wasn't
      adjusting its buffer pointer. Second, there's a white space issue
      fixed. Third, the logic in function gfs2_rbm_from_block was optimized
      a bit. Lastly, a check for goal block overflows was added to function
      gfs2_alloc_blocks.

      GFS2: Fix case where reservation finished at end of rgrp · 5d50d532
      Steven Whitehouse authored
      One corner case which the original patch failed to take into
      account was when there is a reservation which ended such that
      the following block was one beyond the end of the rgrp in
      question. This extra test fixes that case.

      Michel Lespinasse authored
      gfs2 calls RB_EMPTY_NODE() to check if nodes are not on an rbtree.
      The corresponding initialization function is RB_CLEAR_NODE().
      rb_init_node() was never clearly defined and is going away.

      GFS2: Replace rgblk_search with gfs2_rbm_find · 5b924ae2
      Steven Whitehouse authored
      This is part of a series of patches which are introducing the
      gfs2_rbm structure throughout the block allocation code. The
      main aim of this part is to create a search function which can
      deal directly with struct gfs2_rbm. In this case it specifies
      the initial position at which to start the search and also the
      point at which the search terminates.
      
      The net result of this is to clean up the search code and make
      it rather more readable, and the various possible exceptions which
      may occur during the search are partitioned into their own functions.
      
      There are some bug fixes too. We should not be checking the reservations
      while allocating extents - the time for that is when we are searching
      for where to put the extent, not when we've already made that decision.
      
      Also, rgblk_search had two uses, and in only one of those cases did
      it make sense to check for reservations. This is fixed in the new
      gfs2_rbm_find function, which has a cleaner interface.
      
      The reservation checking has been improved by always checking for
      contiguous reservations, and returning the first free block after
      all contiguous reservations. This is done under the spin lock to
      ensure consistancy of the tree.
      
      The allocation of extents is now in all cases done by the existing
      allocation code, and if there is an active reservation, that is updated
      after the fact. Again this is done under the spin lock, since it entails
      changing the lookup key for the reservation in question.

      GFS2: Add structure to contain rgrp, bitmap, offset tuple · 4a993fb1
      Steven Whitehouse authored
      This patch introduces a new structure, gfs2_rbm, which is a
      tuple of a resource group, a bitmap within the resource group
      and an offset within that bitmap. This is designed to make
      manipulating these sets of variables easier. There is also a
      new helper function which converts this representation back
      to a disk block address.
      
      In addition, the rbtree nodes which are used for the reservations
      were not being correctly initialised, which is now fixed. Also,
      the tracing was not passing through the inode where it should
      have been. That is mostly fixed aside from one corner case. This
      needs to be revisited since there can also be a NULL rgrp in
      some cases which results in the device being incorrect in the
      trace.
      
      This is intended to be the first step towards cleaning up some
      of the allocation code, and some further bug fixes.

      GFS2: Remove rs_requested field from reservations · 71f890f7
      Steven Whitehouse authored
      The rs_requested field is left over from the original allocation
      code, however this should have been a parameter passed to the
      various functions from gfs2_inplace_reserve() and not a member of the
      reservation structure as the value is not required after the
      initial allocation.
      
      This also helps simplify the code since we no longer need to set
      the rs_requested to zero. Also the gfs2_inplace_release()
      function can also be simplified since the reservation structure
      will always be defined when it is called, and the only remaining
      task is to unlock the rgrp if required. It can also now be
      called unconditionally too, resulting in a further simplification.

      Steven Whitehouse authored
      There were two functions in the xattr code which were nearly
      identical, the only difference being that one was copy data into
      the unstuffed xattrs and the other was copying data out from it.
      
      This patch merges the two functions such that the code which deal
      with iteration over the unstuffed xattrs is no longer duplicated.

      edac_mc: edac_mc_free() cannot assume mem_ctl_info is registered in sysfs. · faa2ad09
      Shaun Ruffell authored
      Fix potential NULL pointer dereference in edac_unregister_sysfs() on
      system boot introduced in 3.6-rc1.
      
      Since commit 7a623c03 ("edac: rewrite the sysfs code to use struct
      device") edac_mc_alloc() no longer initializes embedded kobjects in
      struct mem_ctl_info.  Therefore edac_mc_free() can no longer simply
      decrement a kobject reference count to free the allocated memory unless
      the memory controller driver module had also called edac_mc_add_mc().
      
      Now edac_mc_free() will check if the newly embedded struct device has
      been registered with sysfs before using either the standard device
      release functions or freeing the data structures itself with logic
      pulled out of the error path of edac_mc_alloc().
      
      The BUG this patch resolves for me:

         432          }
      
      and that code block seem to mess things up in several ways (double free, memory
      leak, out-of-bound reads etc.):
      
      L422: The iterator "chn" and bound "tot_channels" are totally wrong. Should be
            "row" and "tot_csrows" respectively. Which means either memory leak, or
            out-of-bound reads (which if does not trigger an immediate page fault
            error, will further lead to kfree() on random addresses).
      
      L425: The inner loop is reusing the same iterator "chn" as the outer loop,
            which could lead to premature end of the outer loop, and hence memory leak.
      
      L429: The array index 'i' in mci->csrows[i] is a temporary value used in
            previous loops, and won't change at all in the current loop. Which
            means either out-of-bound read and possibly kfree(random number), or the
            same mci->csrows[i] get freed once and again, and possibly double free
            for the kfree(csr) in L427.
      
      L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory.
      
      The buggy code was introduced by commit de3910eb ("edac: change the mem
      allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1
      merge window. Fix it by freeing up resources in this order:
      
        free csrows[i]->channels[j]
        free csrows[i]->channels
        free csrows[i]
        free csrows

       2) When IPSEC policies change, we do not properly make sure that cached
          routes (which could now be stale) throughout the system will be

      10) The removal of the conditional compilation of the clk support code
          in the stmmac driver broke things.  This is because the interfaces
          used are the ones that don't also perform the enable/disable of the
          clk.  Fix from Stefan Roese.
      
      11) The QFQ packet scheduler can record out of range virtual start
          times, resulting later in misbehavior and even crashes.  Fix from
          Paolo Valente.
      
      12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the
          receiver when the advertised receive window goes to zero.  Detect
          this case and force the processing of the IOAT DMA queue when it

      2) Wei Yongjun noticed that module_alloc() on sparc can return an
         error pointer, but that's not allowed.  module_alloc() should
         return only a valid pointer, or NULL.

      sparc: fix the return value of module_alloc() · a9e8d1a6
      Wei Yongjun authored
      In case of error, function module_alloc() in other platform never
      returns ERR_PTR(), and all of the user only check for NULL, so
      we'd better return NULL instead of ERR_PTR().
