From: Arnaldo Carvalho de Melo Date: Wed, 9 Dec 2009 22:09:38 +0000 (-0200) Subject: perf symbols: perf_header__read_build_ids() offset'n'size should be u64 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=716d69e4fda0563ef67d62ee44baa17b377b9b23;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf symbols: perf_header__read_build_ids() offset'n'size should be u64 As off_t is a long, so breaking things on 32-bit land. Now buildids work on 32-bit land.
