Some of the tests which require a block device for their execution are skipped when runltp is run without any block device being specified on commandline.Most of such tests are from syscalls group and as a work around to make these tests run even when no block device is specified,I have made use of loopback device to create a block device with ext4 filesystem. So,runltp is modified to create a block device and set the values for DEVICE and DEVICE_FS_TYPE accordingly.
Following are the skipped tests, ---- inotify03 inotify03 -D DEVICE -T DEVICE_FS_TYPE mount01 mount01 -D DEVICE -T DEVICE_FS_TYPE mount02 mount02 -D DEVICE -T DEVICE_FS_TYPE mount03 mount03 -D DEVICE -T DEVICE_FS_TYPE mount04 mount04 -D DEVICE -T DEVICE_FS_TYPE umount01 umount01 -D DEVICE -T DEVICE_FS_TYPE umount02 umount02 -D DEVICE -T DEVICE_FS_TYPE umount03 umount03 -D DEVICE -T DEVICE_FS_TYPE ---- Please review the patch and let me know if any more changes are needed.
