7 * These are exactly the same definitions as in fs.h, but the names are
8 * changed so that this file can be included in both kernel and user files.

13 #define HOSTFS_ATTR_GID 4

26 * If you are very careful, you'll notice that these two are missing:
28 * #define ATTR_KILL_SUID 2048
29 * #define ATTR_KILL_SGID 4096
31 * and this is because they were added in 2.5 development in this patch:
33 * http://linux.bkbits.net:8080/linux-2.5/

37 * Actually, they are not needed by most ->setattr() methods - they are set by
38 * callers of notify_change() to notify that the setuid/setgid bits must be
40 * notify_change() will delete those flags, make sure attr->ia_valid & ATTR_MODE
41 * is on, and remove the appropriate bits from attr->ia_mode (attr is a
42 * "struct iattr *"). -BlaisorBlade
