      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_exit_ptr is changed to mlog(0.
      All those mlog(0,...) will be replaced with trace events later.

      ocfs2: Remove ENTRY from masklog. · ef6b689b

      ENTRY is used to record the entry 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.
      So for mlog_entry_void, we just remove it.
      for mlog_entry(...), we replace it with mlog(0,...), and they
      will be replace by trace event 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: update comments in masklog.h · 2b53bc7b
      Coly Li authored
      In the mainline ocfs2 code, the interface for masklog is in files under
      /sys/fs/o2cb/masklog, but the comments in fs/ocfs2/cluster/masklog.h
      reference the old /proc interface.  They are out of date.
      This patch modifies the comments in cluster/masklog.h, which also provides
      a bash script example on how to change the log mask bits.

      ocfs2: Implementation of local and global quota file handling · 9e33d69f
      Jan Kara authored
      For each quota type each node has local quota file. In this file it stores
      changes users have made to disk usage via this node. Once in a while this
      information is synced to global file (and thus with other nodes) so that
      limits enforcement at least aproximately works.
      Global quota files contain all the information about usage and limits. It's
      mostly handled by the generic VFS code (which implements a trie of structures
      inside a quota file). We only have to provide functions to convert structures
      from on-disk format to in-memory one. We also have to provide wrappers for
      various quota functions starting transactions and acquiring necessary cluster
      locks before the actual IO is really started.

      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.
