Revision 5756b76e4db643d8f75174a9a50038523d4b9e32 authored by Jan Beulich on 05 March 2012, 16:49:24 UTC, committed by Linus Torvalds on 06 March 2012, 16:22:26 UTC
kasprintf() (and potentially other functions that I didn't run across so far) want to evaluate argument lists twice. Caring to do so for the primary list is obviously their job, but they can't reasonably be expected to check the format string for instances of %pV, which however need special handling too: On architectures like x86-64 (as opposed to e.g. ix86), using the same argument list twice doesn't produce the expected results, as an internally managed cursor gets updated during the first run. Fix the problem by always acting on a copy of the original list when handling %pV. Signed-off-by: Jan Beulich <jbeulich@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
