FreeBSD seems to have added UF_HIDDEN to struct stat.st_flags back in 2006: http://updraft3.jp.freebsd.org/cgi/query-pr.cgi?pr=kern/94519 They also have other useful flags like immutable, append only, no dump, etc that certainly apply to ext3 too (i.e. these are settable with chattr). Sounds like a very good idea to me. There is even availible unused space in the userspace/glibc struct stat to add them, and there seems to be some in the kernel struct too. They also have chflags/lchflags/fchflags to change these attributes. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
