[PATCH] Make div64_u64() precise on 32bit platforms
On Mon, 2 Aug 2010 18:09:51 +0200 Oleg Nesterov <oleg(a)redhat.com> wrote: We have a bugreport which blames div64_u64() on 32bit platforms. However, the code obviously doesn't even try to pretend it can do the 64bit division precisely. If there is something in the high word of divisor, ... 9 Aug 2010 13:27

v2.6.35-git2 SELinux build failure
Commit b782e0a6, introduced in v2.6.35-git2, uses FILE__AUDIT_ACCESS without actually defining it: security/selinux/hooks.c:2644: error: 'FILE__AUDIT_ACCESS' undeclared (first use in this function) I first noticed this in 2.6.35-git6, and it is still broken in 2.6.35-git7.
