With user namespaces enabled building f2fs fails with:
CC fs/f2fs/acl.o
fs/f2fs/acl.c: In function ‘f2fs_acl_from_disk’:
fs/f2fs/acl.c:85:21: error: ‘struct posix_acl_entry’ has no member named ‘e_id’
make[2]: *** [fs/f2fs/acl.o] Error 1
make[2]: Target `__build' not remade because of errors.
e_id is a backwards compatibility field only used for file systems
that haven't been converted to use kuids and kgids. When the posix
acl tag field is neither ACL_USER nor ACL_GROUP assigning e_id is
unnecessary. Remove the assignment so f2fs will build with user
namespaces enabled.

Barring other feedback I will push this change to Linus with my other
namespace bug fixes in the next day or two.
