  21 # TEST:
  22 #   NAME:       test_robind.sh
  23 #   FUNCTIONALITY:  File system tests for normal mount, bind mount and RO mount
  24 #
  25 #   DESCRIPTION:    Performs filesystems tests for RO mount.
  26 #     For filesystem's like ext2, ext3, reiserfs, jfs & xfs.
  27 #     This test creates an image-file and
  28 #        a)  mounts on dir1,
  29 #        b)  mount --bind dir2
  30 #        c)  mount -o remount,ro
  31 #       It verifies the tests on a) and b) works correctly.
  32 #     For the c) option it checks that the tests are not able to write into dir.
  33 #     Then it executes the tests from flat-file  {LTPROOT}/testscripts/fs_ro_tests
  34 #     Check the logs /tmp/fs$$/errs.log and /tmp/fs$$/pass.log for pass/failures.
