# Mount a go-fuse loopback filesystem in /tmp and run fsstress against it
# in an infinite loop, only exiting on errors.
#
# When called as "fsstress-gocryptfs.bash", a gocryptfs filesystem is tested
# instead.
#
# This test used to fail on older go-fuse versions after a few iterations with
# errors like this:
# "rm: cannot remove /tmp/b/fsstress.2/pd/d1XXX/f4a: No such file or directory"
#
# Nowadays it should pass an indefinite number of iterations.
