Summary: drm modules won't compile with 2.6.21-rc6 (m_insert_pfn
clash)
Product: DRI
Version: DRI CVS
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: highest
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
CC: [EMAIL PROTECTED]
It looks like that latest (as of writing [EMAIL PROTECTED]) kernel contains
function named vm_insert_pfn in /mm/memory.c and /mm/mm.h (see
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=e0dc0d8f4a327d033bfb63d43f113d5f31d11b3c
for specific check-in). Unfortunately vm_insert_pfn is also used in
drm_compat.c thus resulting in naming clash. At a first glance they both differ
in code very much.
The result of make is
/home/michal/nouveau/drm/linux-core/drm_compat.c:190: error: static declaration
of ‘vm_insert_pfn’ follows non-static declaration
include/linux/mm.h:1126: error: previous declaration of ‘vm_insert_pfn’ was
here
The bug was found on Ubuntu Feisty with latest kernel packages installed (which
apparently is 2.6.20. uname -r gives 2.6.20-14-generic) 2.6.20 from gentoo does
not have this problem.
