default_acl and acl of newly created inode will be initiated
as ACL_NOT_CACHED in vfs function inode_init_always() and later
will be updated by calling xxx_init_acl() in specific filesystems.
Howerver, when default_acl and acl are NULL then they keep the value
of ACL_NOT_CACHED, this patch tries to cache NULL for acl/default_acl
in this case.

I'd rephrase the above as: ... then they keep the value of ACL_NOT_CACHED.
This patch changes the code to cache NULL for acl / default_acl in this
