From 3ab04d5cf9736b7a4e9dfcf28285d8663b01aa0e Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 9 Sep 2010 16:38:12 -0700 Subject: [PATCH] vfs: take O_NONBLOCK out of the O_* uniqueness test O_NONBLOCK on parisc has a dual value: #define O_NONBLOCK 000200004 /* HPUX has separate NDELAY & NONBLOCK */ It is caught by the O_* bits uniqueness check and leads to a parisc compile error. The fix would be to take O_NONBLOCK out.
