NACK.

IMO, the proposed change reduces readiability for no good reason.  Most
people touching kernel code have 0444, 0644, 0755, etc. already
hardwired into their pattern recognition neural network, while the POSIX
S_* crap is actually bug food.

PS: no more ill-managed ultra-large patch bombs, *please*.
