# Readme_ROBind has more details on the tests running for ROBIND.
# TEST:
# NAME: test_robind.sh
# FUNCTIONALITY: File system tests for normal mount, bind mount and RO mount
#
# DESCRIPTION: Performs filesystems tests for RO mount.
# For filesystem's like ext2, ext3, reiserfs, jfs & xfs.
# This test creates an image-file and
# a) mounts on dir1,
# b) mount --bind dir2
# c) mount -o remount,ro
# It verifies the tests on a) and b) works correctly.
# For the c) option it checks that the tests are not able to write into dir.
# Then it executes the tests from flat-file {LTPROOT}/testscripts/fs_ro_tests
# Check the logs /tmp/fs$$/errs.log and /tmp/fs$$/pass.log for pass/failures.
