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 --- Hi, V3 revert dname=$(basename $(readlink -f $dev)) line. I think we don't need to check if /sys/fs/${FSTYP}/${dname}/$target is exist in _set_fs_sys_fs_param(). Because if no this file, *echo* will report error, and it will disturb golden file.
