Linux 3.9 14951f22f1cc8375ead345d2ca08455e91f2152b is the first bad commit commit 14951f22f1cc8375ead345d2ca08455e91f2152b Author: Ingo Molnar Date: Sun Sep 29 16:12:54 2013 +0200 Revert "perf symbols: Demangle cloned functions" This reverts commit de95ab53645a2f0015e0f68ee723f18dce2b8b51. Markus Trippelsdorf reported that this commit broke 'perf top': > I just see a gray screen with no text at all. Sometimes the > following error messages are printed: > > *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0 > *** > *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 *** While this code is fixable, the commit itself fails on several levels: - it should have been a separate helper function - why the heck does it do strchr() twice - it casts a const char * over into char * - sloppy style - it's not even a regression fix! So lets revert it and re-try the patch in v3.13.
