From: Ralf Baechle Date: Sat, 28 Mar 2009 00:36:09 +0000 (+0100) Subject: MIPS: Compat: Zero upper 32-bit of offset_high and offset_low. X-Git-Tag: MMI-PSA29.97-13-9~29186^2~18 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d6c178e9694e7e0c7ffe0289cf4389a498cac735;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git MIPS: Compat: Zero upper 32-bit of offset_high and offset_low. Through sys_llseek() arguably should do exactly that it doesn't which means llseek(2) will fail for o32 processes if offset_low has bit 31 set. As suggested by Heiko Carstens.
