      ocfs2: Remove EXIT from masklog. · c1e8d35e
      Tao Ma authored
      
      
      mlog_exit is used to record the exit status of a function.
      But because it is added in so many functions, if we enable it,
      the system logs get filled up quickly and cause too much I/O.
      So actually no one can open it for a production system or even
      for a test.
      
      This patch just try to remove it or change it. So:
      1. if all the error paths already use mlog_errno, it is just removed.
         Otherwise, it will be replaced by mlog_errno.
      2. if it is used to print some return value, it is replaced with
         mlog(0,...).
      mlog_exit_ptr is changed to mlog(0.
      All those mlog(0,...) will be replaced with trace events later.

      ocfs2: allocation reservations · d02f00cc
      Mark Fasheh authored
      
      
      This patch improves Ocfs2 allocation policy by allowing an inode to
      reserve a portion of the local alloc bitmap for itself. The reserved
      portion (allocation window) is advisory in that other allocation
      windows might steal it if the local alloc bitmap becomes
      full. Otherwise, the reservations are honored and guaranteed to be
      free. When the local alloc window is moved to a different portion of
      the bitmap, existing reservations are discarded.
      
      Reservation windows are represented internally by a red-black
      tree. Within that tree, each node represents the reservation window of
      one inode. An LRU of active reservations is also maintained. When new
      data is written, we allocate it from the inodes window. When all bits
      in a window are exhausted, we allocate a new one as close to the
      previous one as possible. Should we not find free space, an existing
      reservation is pulled off the LRU and cannibalized.

      ocfs2: Add extent tree operation for xattr value btrees · f56654c4
      Tao Ma authored
      
      
      Add some thin wrappers around ocfs2_insert_extent() for each of the 3
      different btree types, ocfs2_inode_insert_extent(),
      ocfs2_xattr_value_insert_extent() and ocfs2_xattr_tree_insert_extent(). The
      last is for the xattr index btree, which will be used in a followup patch.
      
      All the old callers in file.c etc will call ocfs2_dinode_insert_extent(),
      while the other two handle the xattr issue. And the init of extent tree are
      handled by these functions.
      
      When storing xattr value which is too large, we will allocate some clusters
      for it and here ocfs2_extent_list and ocfs2_extent_rec will also be used. In
      order to re-use the b-tree operation code, a new parameter named "private"
      is added into ocfs2_extent_tree and it is used to indicate the root of
      ocfs2_exent_list. The reason is that we can't deduce the root from the
      buffer_head now. It may be in an inode, an ocfs2_xattr_block or even worse,
      in any place in an ocfs2_xattr_bucket.

      kset: convert ocfs2 to use kset_create · c60b7178
      Greg Kroah-Hartman authored
      
      
      Dynamically create the kset instead of declaring it statically.
      
      Also use the new kobj_attribute which cleans up this file a _lot_.

      kobject: remove struct kobj_type from struct kset · 3514faca
      Greg Kroah-Hartman authored
      
      
      We don't need a "default" ktype for a kset.  We should set this
      explicitly every time for each kset.  This change is needed so that we
      can make ksets dynamic, and cleans up one of the odd, undocumented
      assumption that the kset/kobject/ktype model has.
      
      This patch is based on a lot of help from Kay Sievers.

      sysfs: kill unnecessary attribute->owner · 7b595756
      Tejun Heo authored
      sysfs is now completely out of driver/module lifetime game.  After
      deletion, a sysfs node doesn't access anything outside sysfs proper,
      so there's no reason to hold onto the attribute owners.  Note that
      often the wrong modules were accounted for as owners leading to
      accessing removed modules.
      
      This patch kills now unnecessary attribute->owner.  Note that with
      this change, userland holding a sysfs node does not prevent the
      backing module from being unloaded.
      
      For more info regarding lifetime rule cleanup, please read the
      following message.

      (tweaked by Greg to not delete the field just yet, to make it easier to
      merge things properly.)
