..._old_inode_init_security() - Request LSMs to fill xattrs if only value (not the triple) is provided to security_old_inode_init_security(), to avoid unnecessary memory allocation v2: - rewrite selinux_old_inode_init_security() to use security_inode_init_security() - add lbs_xattr field to lsm_blob_sizes structure, to give the ability to LSMs to reserve slots in the xattr array (suggested by Casey) - add new parameter base_slot to inode_init_security hook definition v1: - add calls to reiserfs_security_free() and initialize sec->value to NULL (suggested by Tetsuo and Mimi) - change definit...

...dency comment in patch 1 (suggested by Mimi) - Restore check of -EOPNOTSUPP status in ocfs2_mknod() and ocfs2_symlink() (reported by Mimi) - Add explanation in evm_inode_init_security() why walking through the xattrs array is safe (suggested by Mimi) - Document the lbs_xattr field of struct lsm_blob_sizes (suggested by Casey) - Move documentation changes of the inode_init_security hook to security.c, after LSM documentation reorganization by Paul - Use attributes in plural form in the description of the xattrs parameter of smack_inode_init_security() - Check xattr name instead of xattr value...
