IJ49852: BLOCK COUNT IS SHOWN AS ONE AFTER THE AFM EVICTION

APAR status

• Closed as program error.

Error description

• With showNonZeroBlockCountForNonEmptyFiles set, block count is
  always shown as one to report fake block count . This is a
  work-around for faulty applications (e.g., Gnu tar --sparse)
  that erroneously assume  zero st_blocks means the file contains
  no nonzero bytes.
