       This file lists NFS-Ganesha Cache config options.

   CACHEINODE {}
       NParts (uint32, range 1 to 32633, default 7)
              Partitions in the Cache_Inode tree.

       Cache_Size(uint32, range 1 to UINT32_MAX, default 32633)
              Per-partition hash table size.

       Use_Getattr_Directory_Invalidation(bool, default false)
              Use getattr for directory invalidation.

       Dir_Max_Deleted(uint32, range 1 to UINT32_MAX, default 65536)
              Max size of per-directory cache of removed entries

       Dir_Max(uint32, range 1 to UINT32_MAX, default 65536)
              Max size of per-directory dirent cache

       Dir_Chunk(uint32, range 0 to UINT32_MAX, default 128)
              Size  of  per-directory  dirent  cache  chunks,  0  means directory chunking is not
              enabled.

       Detached_Mult(uint32, range 1 to UINT32_MAX, default 1)
              Max number of detached directory entries expressed as a multiple of the chunk size.

       Entries_HWMark(uint32, range 1 to UINT32_MAX, default 100000)
              The point at which object cache entries will start being reused.

       LRU_Run_Interval(uint32, range 1 to 24 * 3600, default 90)
              Base interval in seconds between runs of the LRU cleaner thread.

       Cache_FDs(bool, default true)
              Whether to cache open files

       FD_Limit_Percent(uint32, range 0 to 100, default 99)
              The percentage of the system-imposed maximum of file descriptors at  which  Ganesha
              will deny requests.

       FD_HWMark_Percent(uint32, range 0 to 100, default 90)
              The  percentage  of  the  system-imposed  maximum  of  file descriptors above which
              Ganesha will make greater efforts at reaping.

       FD_LWMark_Percent(uint32, range 0 to 100, default 50)
              The percentage of the  system-imposed  maximum  of  file  descriptors  below  which
              Ganesha will not reap file descriptors.

       Reaper_Work(uint32, range 1 to 2000, default 0)
              Roughly,  the  amount  of  work  to do on each pass through the thread under normal
              conditions.  (Ideally, a multiple  of  the  number  of  lanes.)   This  setting  is
              deprecated.  Please use Reaper_Work_Per_Lane

       Reaper_Work_Per_Lane(uint32, range 1 to 2000, default 50)
              This  is  the  numer  of  handles per lane to scan when performing LRU maintenance.
              This task is performed by the Reaper thread.

       Biggest_Window(uint32, range 1 to 100, default 40)
              The largest window (as a percentage of the system-imposed limit  on  FDs)  of  work
              that we will do in extremis.

       Required_Progress(uint32, range 1 to 50, default 5)
              Percentage of progress toward the high water mark required in in a pass through the
              thread when in extremis

       Futility_Count(uint32, range 1 to 50, default 8)
              Number of failures to approach the high watermark before we disable  caching,  when
              in extremis.

       Retry_Readdir(bool, default false)
              Behavior  for  when  readdir  fails  for some reason: * true will ask the client to
              retry later, * false will give the
