XFS add more configurations in /sys/fs/xfs recently. For use them, this patch add some common functions for: 1. "require" a file/dir in /sys/fs/${FSTYP}. 2. write a file in /sys/fs/${FSTYP}. For common use, these functions can be used by other filesystems. Signed-off-by: Zorro Lang <zlang@redhat.com> --- Hi, This V2 patch follow Eric's suggestions: 1. remove useless functions: _require_scratch_sys_fs(), _enable_xfs_fail_at_unmount() and _disable_xfs_fail_at_unmount(). 2. change _require_sys_fs() to _require_fs_sys_fs(). 3. change _set_sys_fs_param() to _set_fs_sys_fs_param(). 4. Don't mkfs in _require_fs_sys_fs(). 5. use a tmp mnt dir to instead of SCRATCH_MNT in _require_fs_sys_fs().
