      Apparently, the tools/testing version dates to a few flags ago, and
      we've sprouted 4 new ones since.  Keep in sync with the value in the

      mm: move swap-in anonymous page into active list · 1a8018fb
      Minchan Kim authored
      Every swap-in anonymous page starts from inactive lru list's head.  It
      should be activated unconditionally when VM decide to reclaim because
      page table entry for the page always usually has marked accessed bit.
      Thus, their window size for getting a new referece is 2 * NR_inactive +
      NR_active while others is NR_inactive + NR_active.
      
      It's not fair that it has more chance to be referenced compared to other
      newly allocated page which starts from active lru list's head.
      
      Johannes:
      
      : The page can still have a valid copy on the swap device, so prefering to
      : reclaim that page over a fresh one could make sense.  But as you point
      : out, having it start inactive instead of active actually ends up giving it
      : *more* LRU time, and that seems to be without justification.
      
      Rik:
      
      : The reason newly read in swap cache pages start on the inactive list is
      : that we do some amount of read-around, and do not know which pages will
      : get used.
      :
      : However, immediately activating the ones that DO get used, like your patch
      : does, is the right thing to do.

      The important bits from the above is that filemap_map_pages() is calling
      into the page allocator while holding rcu_read_lock (sleeping is not
      allowed inside RCU read-side critical sections).
      
      According to Kirill Shutemov, the prefaulting code in do_fault_around()
      is supposed to take care of this, but missing error handling means that
      the allocation failure can go unnoticed.
      
      We don't need to return VM_FAULT_OOM (or any other error) here, since we
      can just let the normal fault path try again.

      We found a BUG situation that lockres is migrated during deref described

      ocfs2: retry on ENOSPC if sufficient space in truncate log · 2070ad1a
      Eric Ren authored
      The testcase "mmaptruncate" in ocfs2 test suite always fails with ENOSPC
      error on small volume (say less than 10G).  This testcase repeatedly
      performs "extend" and "truncate" on a file.  Continuously, it truncates
      the file to 1/2 of the size, and then extends to 100% of the size.  The
      main bitmap will quickly run out of space because the "truncate" code
      prevent truncate log from being flushed by
      ocfs2_schedule_truncate_log_flush(osb, 1), while truncate log may have
      cached lots of clusters.
      
      So retry to allocate after flushing truncate log when ENOSPC is
      returned.  And we cannot reuse the deleted blocks before the transaction
      committed.  Fortunately, we already have a function to do this -
      ocfs2_try_to_free_truncate_log().  Just need to remove the "static"
      modifier and put it into the right place.
      
      The "unlock"/"lock" code isn't elegant, but there seems to be no better
      option.

      ocfs2: ensure that dlm lockspace is created by kernel module · 01a36b67
      Gang He authored
      We encountered a bug from the customer, the user did a fsck.ocfs2 on the
      file system and exited unusually, the lockspace (with LVB size = 32) was
      left in the kernel space, next, the user mounted this file system, the
      kernel module did not create a new lockspace (LVB size = 64) via calling
      dlm_new_lockspace() function in mounting stage, just used the existing
      lockspace, created by the user space tool, this would lead the user was
      not able to mount this file system from the other nodes, with the error
      message like:
      
        dlm: 032F5......: config mismatch: 64,0 nodeid 177127961: 32,0
        (mount.ocfs2,26981,46):ocfs2_dlm_init:2995 ERROR: status = -71
        ocfs2_mount_volume:1881 ERROR: status = -71
        ocfs2_fill_super:1236 ERROR: status = -71
      
      The user found it very difficult to find the root cause, then, we
      brought out this patch to relieve such problem.
      
      First, we add one more flag in calling dlm_new_lockspace() function, to
      make sure the lockspace is created by kernel module itself, and this
      change will not affect the backward compatibility.
      
      Second, the obvious error message is reported in the kernel log, let the
      user be more easy to find the root cause.
      
      This patch will be used to insure the dlm lockspace is created by kernel
      module when mounting a ocfs2 file system.  There are two ways to create
      a lockspace, from user space and kernel space, but the same name
      lockspaces probably have different lvblen lengths/flags.
      
      To avoid this mix using, we add one more flag DLM_LSFL_NEWEXCL, it will
      make sure the dlm lockspace is created by kernel module when mounting.
      Secondly, if a user space program (ocfs2-tools) is running on a file
      system, the user tries to mount this file system in the cluster, DLM
      module will return a -EEXIST or -EPROTO errno, we should give the user a
      obvious error message, then, the user can let that user space tool exit
      before mounting the file system again.

      Linus Torvalds authored
      Pull btrfs updates from Chris Mason:
       "This pull is dedicated to Josef's enospc rework, which we've been
        testing for a few releases now.  It fixes some early enospc problems
        and is dramatically faster.
      
        This also includes an updated fix for the delalloc accounting that
        happens after a fault in copy_from_user.  My patch in v4.7 was almost
        but not quite enough"
