# This script checks if use-readdirp option works as accepted in mount options

# Note on re-reading $M0/new after enabling root-squash:
# Since we have readen it once, the file is present in various caches.
# In order to actually fail on second attempt we must:
# 1) drop kernel cache
# 2) make sure FUSE does not cache the entry. This is also
#    in the kernel, but not flushed by a failed umount.
#    Using $GFS enforces this because it sets --entry-timeout=0
# 3) make sure reading new permissins does not produce stale
#    information from glusterfs metadata cache. Setting volume
#    option performance.stat-prefetch off enforces that.
