dentry_state

Status of the directory cache. Since directory entries are dynamically allocated and deallocated, this file indicates the current status. It holds six values of which only the first three are used:

  • nr_dentry - number of dentries currently allocated
  • nr_unused - nuber of unused dentries
  • age_limit - seconds after the entry may be reclaimed, when memory is short

Last three values are not used and are always zero.
