Exactly: it defined +asmlinkage int sys_fsattr(const char * filename, unsigned int len, + const char *in, char *out) which also allows the vector of flag bits to grow beyond 4 bytes in the future. It mapped all of the ext3 attributes correctly to the portable ATTR_FLAG_* definitions and allowed attributes to be set on device files (which was the whole reason for it at the time). The only thing missing was the lfsattr variant. --Stephen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/
