Title:
  xfs_btree_cur leak

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  There appears to be a kernel memory leak of xfs_btree_cur in recent
  Precise kernels (3.2.0-45 and -63 are affected, for sure).   The slab
  can grow unbounded; we've seen it grow larger than 32GB via slabtop.
  The affected hosts have XFS mounted on / (root filesystem).

  We have another host running 3.2.0-38 in which we do not see this
  problem (it has a 37TB XFS filesystem mounted, but not on root).

  Upgrading to the latest 3.8.0-41 kernel via linux-generic-lts-raring
  seems to resolve the issue.
