From 26ca0bca9bd5e23b1d31bc6dfb6d58b62143447b Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Tue, 27 Jan 2009 22:39:50 +0200 Subject: drm compat: fix euid for >=2.6.28 drm_fops.c reads the current process' EUID directly from task_struct. Apparently starting in 2.6.28-rc4 this fails to build. In Linus' tree, commit b6dff3ec5e116e3af6f537d4caedcad6b9e5082a "CRED: Separate task security context from task_struct" moves the euid field from task_struct to another struct. Earlier commit 9e2b2dc4133f65272a6d3c5dcb2ce63f8a87cae9 "CRED: Introduce credential access wrappers" implements the wrapper macros to access e.g. euid. This is in 2.6.27-rc4, and this contains the definition of current_euid() that will be used in the DRM compatibility header for kernels before 2.6.27. That commit also creates , which contains the upstream definition of current_euid(). drm_fops.c is fixed to use current_euid(), and drm_compat.h will offer the compatibility definition for kernels <2.6.27.
