The main objection raised was the use of may_delete and may_create inode
operations callback. They are gone now and we have MAY_* flags as
favoured by Al Viro.  The new MAY_* flags added are 

#define MAY_CREATE_FILE 128
#define MAY_CREATE_DIR 256
#define MAY_DELETE_CHILD 512
#define MAY_DELETE_SELF 1024
#define MAY_TAKE_OWNERSHIP 2048
#define MAY_CHMOD 4096
#define MAY_SET_TIMES 8192

IMHO we are ready to get first 11 patches upstream in the next merge
window. ie the below set of patches.

vfs: Make acl_permission_check() work for richacls
vfs: Add permission flags for setting file attributes
vfs: Make the inode passed to inode_change_ok non-const
vfs: Add delete child and delete self permission flags
vfs: Add new file and directory create permission flags
vfs: Optimize out IS_RICHACL() if CONFIG_FS_RICHACL is not defined
vfs: Add IS_RICHACL() test for richacl support
vfs: Add generic IS_ACL() test for acl support
vfs: Add a comment to inode_permission()
vfs: Pass all mask flags down to iop->check_acl
vfs: Indicate that the permission functions take all the MAY_* flags
