From: Jeremy Fitzhardinge Date: Thu, 12 Jun 2008 08:48:00 +0000 (+0200) Subject: always_inline timespec_add_ns X-Git-Tag: v2.6.26-rc6~7^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9412e28649d0272df5e4af57bb378926fd4df580;p=platform%2Fkernel%2Flinux-stable.git always_inline timespec_add_ns timespec_add_ns is used from the x86-64 vdso, which cannot call out to other kernel code. Make sure that timespec_add_ns is always inlined (and only uses always_inlined functions) to make sure there are no unexpected calls.
